## Summary
Finally, I have received my device and got to chance to work on OTA.
https://github.com/crosspoint-reader/crosspoint-reader/issues/176
* **What is the goal of this PR?** (e.g., Implements the new feature for
file uploading.)
Existing OTA functionality is very buggy, many of times (I would say 8
out of 10) are end up with fail for me. When the time that it works it
is very slow and take ages. For others looks like end up with crash or
different issues.
* **What changes are included?**
To be honest, I'm not familiar with Arduino APIs of OTA process, but
looks like not good as much esp-idf itself. I always found Arduino APIs
very bulky for esp32. Wrappers and wrappers.
## Additional Context
Right now, OTA takes ~ 3min 10sec (of course depends on size of .bin
file). Can be tested with playing version info inside from
`platform.ini` file.
```
[crosspoint]
version = 0.14.0

## Summary

authentication module, Implements the new feature for
file uploading.)
This PR refactors the semantic version comparison logic used during OTA
update checks.
Memory stats before :
RAM: [=== ] 30.8% (used 101068 bytes from 327680 bytes)

Memory stats before :
RAM: [=== ] 30.8% (used 101068 bytes from 327680 bytes)
Flash: [========= ] 85.7% (used **5616870** bytes from 6553600 bytes)
* **What changes are included?**
Replaced std::string::substr() and std::stoi() based parsing with a
lightweight, heap-free approach.
Version parsing is now done in a single pass without creating temporary
std::string objects.
Behavior remains identical: versions are still compared as
MAJOR.MINOR.PATCH.
## Additional Context
`std::string::substr() ` creates a new string and performs heap
allocation
* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks, specific areas to
focus on).
## Summary
* Adds support for OTA
* Gets latest firmware bin from latest GitHub release
* I have noticed it be a little flaky unpacking the JSON and
occasionally failing to start
