/!\ This PR depends on https://github.com/crosspoint-reader/crosspoint-reader/pull/732 being merged first Also requires the https://github.com/open-x4-epaper/community-sdk/pull/18 PR Lyra theme icons on the home menu, in the file browser and on empty book covers     - Added a function to the open-x4-sdk renderer to draw transparent images - Added a scripts/convert_icon.py script to convert svg/png icons into a C array that can be directly imported into the project. Usage: ```bash python ./scripts/convert_icon.py 'path/to/icon.png' cover 32 32 ``` This will create a components/icons/cover.h file with a C array called CoverIcon, of size 32x32px. Lyra uses icons from https://lucide.dev/icons with a stroke width of 2px, that can be downloaded with any desired size on the site. > The file browser is noticeably slower with the addition of icons, and using an image buffer like on the home page doesn't help very much. Any suggestions to optimize this are welcome. --- While CrossPoint doesn't have restrictions on AI tools in contributing, please be transparent about their usage as it helps set the right context for reviewers. Did you use AI tools to help write this code? _**PARTIALLY**_ The icon conversion python script was generated by Copilot as I am not a python dev. --------- Co-authored-by: Dave Allie <dave@daveallie.com>
