feat(custom-connectionId-userId): WEB-3445 added support for custom connectionId, userId along with some fixes

[ravindra-dyte]

WEB-3445

1. Added support for passing connectionId and speakerUserId.
2. Fixed device audio sampling issues where devices that could only support lower sample rate were not working.
3. Refactored the SDK code to remove non-essential code from the actual SDK build.
4. Added temp fix for Stale AudioContext & processor issue where the old processor is still running and feeding Symbl with audio buffers with all zero values (silent track). This was causing Symbl transcriptions to not show in case of device switch.
5. Updated README for new fields. Added a quick way to test locally.
