Update documentation before 1.0 release

I want to split up the README. The current README is huge and has too many sections that make it hard to follow. I want to split out information that doesn't need to be on the main page into their own .md files. I also want to eliminate non-standard elements like embedded HTML tags and the TOC tag which don't seem to work correctly across all Markdown implementations (GitLab, GitHub, Codeberg). These elements were used because the README was so long it needed a TOC and toggleable hidden sections but I think it would be better to move these to their own documents. Also, it makes the documentation easier to read in plaintext.

I also want to move the SDK and RGBController API documentation from the wiki into the project itself so that it can be updated in sync with the protocol changes.
