perf: new file-based cache that ensures correct rtp order (#532) 

* perf: new file-based cache that ensures rtp is alweays correct and will cache all files, including those after startup

* refactor: new cache

* test: fix tests

* fix(cache): cache file names on Windows

* feat(cache): allow to disable the cache

* docs: updated cache settings
