* Further auth requests consistency fixes
- Generated device UUIDs are lowercase, whereas they're uppercase in MCL
- TitleId in SISU authenticate is supposed to be a string (it is in MCL)
- UseModernGamertag in SISU authorize, on the other hand, is a boolean
- Clarified charset of our requests like MCL does
- Specified rng gen call to generate u8 to fix compile error (???)
* Enable deflate, gzip and brotli compression support
