refactor!: replace unnecessary classes with pure functions (#468)
* deps: update linkedom
* refactor!: remove YTNodeGenerator in favour of namespaced pure functions
BREAKING CHANGES:
- Removes `YTNodeGenerator` from `import('youtubei.js').Generator` and exposes its functions directly in `import('youtubei.js').Generator`
* refactor!: replace Parser class with pure functions
- Remove Parser class in favour of pure functions
- Merge duplicate classes `AppendContinuationItemsAction` into a single class
- Move continuation parsers into a seperate file
- Add better custom logging support to parser methods as per issue #460
* refactor!: replace Proto class with pure functions
* chore: update package-lock.json
* refactor!: replace FormatUtils with pure functions and JSX components
- Replace linkedom DASH manifest generation with a dependency free JSX implementation
- Remove FormatUtils class in favour of pure functions
- Remove DOMParser requirement
- Remove duplicate types
* refactor: implement changes from #462
* chore: lint
* fix: deno support
* fix: render valid xml document
* fix: wrong function call in DashUtils
* fix: typo in parser
Co-authored-by: LuanRT <luan.lrt4@gmail.com>
* refactor!: move streaming info logic into seperate function
This allows users to access the same data available in the dash manifest while also simplifying the manifest generation
* chore: lint
* refactor: readability improvements & fixes
Remove redundant getAudioTrackGroups
General readability improvements in StreamingInfo.ts
Share response object between `getBitrate` and `getMimeType` as to not make duplicate requests
* build: remove unnecessary step in deno build

* refactor: move types to `types` directory
* docs: add back comments lost during refactor
* chore: lint
