- Renamed `getIndentWidth` to `getTextAdvanceX`
- Collapsed `Style` and `BlockStyle` into a single struct, and switched to using bitflag setup for determining font style in `EpdFontFamily::Style`, including underlined text
- Added caching for parsed CSS rules
- Reverted changes for fixing spurious spaces
- Skipped loading CSS on Sleep and HomeScreen activities, since we only need BookMetadata and the cover image
- Reverted changes to BookMetadataCache, since we don't need to cache the individual CSS files and can instead use the parsed CSS rules (and the new cache file for those)
- Switched intermediary values to direct assignment in `CssParser.cpp`
- Added function in `BlockStyle.h` to directly convert from a `CssStyle` to a `BlockStyle`, as well as combined multiple `BlockStyle`s together for nested elements that should inherit the parent's style when the child's is unspecified
- Updated names of variables in `CssStyle` to match those of the CSS they represent (e.g. alignment -> textAlign, indent -> textIndent)
- General cleaning up and simplifying the code
## Summary
* **What is the goal of this PR?** Simple quality of life, ease
maintenance
* **What changes are included?**
Update fontconvert.py to include the command used to generate each font
file in the header comment, making it easier to regenerate fonts when
needed.
I plan on adding options to this scripts (kerning, and maybe ligatures),
thus knowing which command was used, even with already existing options
like `--additional-intervals`, is important.

The current behavior of rendering `?` for an unknown Unicode character
can be hard to distinguish from a typo. Use the standard Unicode
"replacement character" instead, that's what it's designed for:
https://en.wikipedia.org/wiki/Specials_(Unicode_block)
I'm making this PR as a draft because I'm not sure I did everything that
was needed to change the character set covered by the fonts. Running
that script is in its own commit. If this is proper, I'll rebase/squash
into one commit and un-draft.

## Summary
* Update EpdFontFamily::Style to be u8 instead of u32 (saving 3 bytes
per word)
* Update layout width/height to be u16 from int
* Update page element count to be u16 from u32
* Update text block element count to be u16 from u32
* Bumped section bin version to version 8
## Summary
* Swap from Aleo to Bookerly for wider glyph support
* Swap from Space Grotesk to a small Noto Sans
## Additional Context
* 0.11.0 swapped to Aleo which has a few issues (things like Cyrillic
support for eg)
Replace linear O(n) search with binary search O(log n) for unicode
interval lookup. Korean fonts have many intervals (~30,000+ glyphs), so
this improves text rendering performance during page navigation.
## Summary
* **What is the goal of this PR?** (e.g., Fixes a bug in the user
authentication module, Implements the new feature for
file uploading.)
Replace linear `O(n)` glyph lookup with binary search `O(log n)` to
improve text rendering performance during page navigation.
* **What changes are included?**
- Modified `EpdFont::getGlyph()` to use binary search instead of linear
search for unicode interval lookup
- Added early return for empty interval count
## Additional Context
* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks, specific areas to
focus on).
- Performance implications: Fonts with many unicode intervals benefit
the most. Korean fonts have ~30,000+ glyphs across multiple intervals,
but any font with significant glyph coverage (CJK, extended Latin,
emoji, etc.) will see improvement.
- Complexity: from `O(n)` to `O(log n)` where n = number of unicode
intervals. For fonts with 10+ intervals, this reduces lookup iterations
significantly.
- Risk: Low - the binary search logic is straightforward and the
intervals are already sorted by unicode codepoint (required for the
original early-exit optimization).
## Summary
* adds cyrillic glyphs to pixel arial font, used as Small font in UI
## Additional Context
* with recent changes pixel arial font lost cyrillic glyphs
## Summary
* Previously, only pure black pixels in the font were marked as black,
this expands the black range, and makes the lightest pixels white
## Additional Context
* Noticed personally it was kind of "thin" and washed out a bit, this
massively helps, should also address concerns raised here:
https://github.com/daveallie/crosspoint-reader/discussions/39
* Enhance TOC parsing and chapter selection logic
- Update .gitignore to include additional paths
- Refactor Epub::parseContentOpf to improve NCX item retrieval
- Modify ContentOpfParser to store media type in ManifestItem
- Implement rebuildVisibleSpineIndices in EpubReaderChapterSelectionScreen for better chapter navigation
- Adjust rendering logic to handle empty chapter lists gracefully
* Refactor TOC parsing logic to streamline cover image and NCX item retrieval
* add cyrillic ranges
* revert
* clang format fix
* First pass at moving to SDK EInkDisplay library
* Add 2-bit grayscale text and anti-aliased rendering of text
* Render status bar for empty chapters
* Refresh screen every 15 pages to avoid ghosting
* Simplify boot and sleep screens
* Give FileSelectionScreen task more stack memory
* Move text around slightly on Boot and Sleep screens
* Re-use existing buffer and write to whole screen for 'partial update'
