feat!: implement new API to also handle multiple transcoding outputs (#8

)

* feat!: implement new and better API to also handle multiple transcoding outputs

- Added new, more powerful (though less extensible) DSL to build ffmpeg commands.
- Introduced new concept of long-lived presets and transcoders.
- Removed full output storage during the transcoding process.
- Added built-in presets that can be used out-of-the-box:
  - H.264 360p all the way up to 4K resolution.
  - AAC 128k all the way up to 320k bit rate.
  - DASH H.264 360p all the way up to 4K resolution.
  - DASH AAC 128k all the way up to 320k bit rate.
- Dropped support for Ruby 3.0, Ruby 3.1 is now the minimum supported version.
