#42 replace React with SolidJs

Implements FLASH as SPA with SolidJS #42

Summary:

This PR introduces a basic migration from React to SolidJS, aiming to explore potential performance improvements. This is an early implementation and not yet production-ready. If there's sufficient interest, I will continue to fully migrate the app to a proper SolidJS ecosystem, including linting, testing, and other essential tools.

Notes:

• This is an experimental implementation and not production ready!
• Certain features, such as Flash functionality, may not work as expected, as I'm still exploring SolidJS's behavior in those areas.

Architectural Decision: SPA vs SSR vs SSG

I opted for a **Single Page Application ** architecture in SolidJS, and here's the rationale behind this decision:

1. Performance:
   Since Flash is not content-heavy, an SPA provides better performance after the initial load.

2. SEO Not a Priority:
   Given that SEO isn't a major concern for this project, we don't require the potential SEO benefits of SSR.

3. Dynamic Content:
   Flash seems largely dynamic and user-specific, such as device connection statuses and flashing progress, which aligns well with the SPA model.

4. Offline Capabilities (Future Consideration as there seems to be an ongoing Bounty as well):
   Should we need PWA features in the future, the SPA architecture simplifies the process.

Benchmarks:

• ReactJS Performance:

  

• SolidJS Performance:
