Raylib Gum Runtime should not spam font loading in the log

[profexorgeek]

When creating a list box in my project, Gum seems to be trying to load the font again for every single list item. I think this should not happen and I also think exceptions are happening, possibly because it's trying to open the same file too many times.

The setup for this is complex enough that you'll probably want to use my project. Depending on when you attempt to repro and what I've changed, the steps should be something like this:

1. Run Airpig, you should see an editor screen
2. Click the hamburger menu in the top right
3. Click "Load Project" to bring up the file chooser
4. This will enumerate your MyDocuments folder in a listbox (by default)
5. Observe the debug output
6. You should logs similar to the below

This is the debug output:
