[FEATURE] Add reload on CSS and JS file changes

[pydanny]

Is your feature request related to a problem? Please describe.

I would be nice if FastHTMLLiveReload supported CSS and JS files. See https://discord.com/channels/689892369998676007/1247700012952191049/1281138518382350422

Describe the solution you'd like

Implement this uvicorn main:app --reload-include="*.css" --reload-include="*.js" but in the live_reload.py module and callable from fast_app()

Example code
Provide an example of how you imagine the feature working:

app, rt = fast_app(reload_css=True, reload_js=True)

Problem solved

Makes it easier to work with CSS and JS files. There might still be issues with browser caching.

Confirmation

This may help you @pydanny

Instead of running serve() run serve(reload_includes=["static/*"])

This solved the issue for me as now the app would reload if I'd change some files in my static folder.

Thanks!

In a total facepalm moment I admit to adding that feature to FastHTML #291 😅
