Martin Brook b8e61130f2 refactor: extract shared DitherUtils.h and PixelCache.h
Address review comments #2, #3, and #10:
- Extract duplicated bayer4x4 matrix, applyBayerDither4Level(), and
  drawPixelWithRenderMode() into shared DitherUtils.h
- Extract duplicated PixelCache struct into shared PixelCache.h so both
  JPEG and PNG decoders use the same implementation
- Add MAX_CACHE_BYTES (256KB) size limit to PixelCache::allocate() to
  proactively guard against oversized allocations on embedded targets

This directory is intended for project specific (private) libraries.
PlatformIO will compile them to static libraries and link into the executable file.

The source code of each library should be placed in a separate directory
("lib/your_library_name/[Code]").

For example, see the structure of the following example libraries `Foo` and `Bar`:

|--lib
|  |
|  |--Bar
|  |  |--docs
|  |  |--examples
|  |  |--src
|  |     |- Bar.c
|  |     |- Bar.h
|  |  |- library.json (optional. for custom build options, etc) https://docs.platformio.org/page/librarymanager/config.html
|  |
|  |--Foo
|  |  |- Foo.c
|  |  |- Foo.h
|  |
|  |- README --> THIS FILE
|
|- platformio.ini
|--src
   |- main.c

Example contents of `src/main.c` using Foo and Bar:
```
#include <Foo.h>
#include <Bar.h>

int main (void)
{
  ...
}

```

The PlatformIO Library Dependency Finder will find automatically dependent
libraries by scanning project source files.
