- 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.
