VIDEO-5327 Manual Render Hints example

[PikaJoyce]

JIRA Ticket : VIDEO-5327

This PR is for the new Manual Render Hints modes examples. This also updates twilio-video to use 2.14.0.

Updated UI with some added features:

1. Separated the Switch On/Off buttons
2. Changed the render dimensions to something with wider ranges in between so the difference in quality is obvious
3. Added the bitrate graph from bandwidth constraints example
4. Added some labels for the buttons
5. Separated the helper functions

Possible TODO:

• [ ] Add example for auto mode as well

Looks good to me! But I'll let Mak to approve since he's more familiar with this feature.
