* feat(player): improved decipher logic - Improve the deciphering logic for Signatures and NTokens. - This makes NToken transforms more than 20x faster - It also improves caching of the player drastically, by only keeping the processed responses in binary format. Bringing down the cache per player from 1.8MB to less than 400 bytes * fix: linting errors * fix: tests * refactor: replace TS enum with ordinary JS objects
