* feat(file-sharing): Adds file sharing options.

* squash: Adds missing jsdocs.

* squash: Updates docs for a backend change.

* squash: exports type IFileMetadata.

* feat(conference): Adds a method to request short live tokens.

* squash: Move to ChatRoom.

* feat(conference-request): Attach token to the conference request sent to jicofo.

* squash: Skip adding header when there is no token.

This is the case with permissions reset on backend.

* fix(conference) Fix different bugs with startMuted policy.
If the user changes mute state after joining the call and before the other participats join the call, make sure those state changes are honored.

* feat(startMuted) Ignore startMuted in Jingle from focus.
Apply startMuted policy based on startMuted setting in room meta data.
Moderator settings and AV moderation settings will now be propagated to new endpoints joining the call through room meta data.
Advertise a new capability 'start-muted-room-metadata' to Jicofo for feature detection.

When joining if there was a modification of presence just before sending the presence in the same millisecond we send later a second presence. While testing we see modifications from e2ee which cause the duplicate presence.

It doesn't get translated in the TS build, for one.

Script I used:

```python
import os

for (dirpath, dirnames, filenames) in os.walk('.'):
    if '.git' in dirpath:
        continue
    if 'node_modules' in dirpath:
        continue
    if 'dist' in dirpath:
        continue
    if 'types' in dirpath:
        continue
    for filename in filenames:
        path = os.path.join(dirpath, filename)
        if not path.endswith('.js') and not path.endswith('.ts'):
            continue
        #print(path)
        with open(path, 'r+') as f:
            #print(f)
            data = f.read()
            if '__filename' in data:
                p, ext = os.path.splitext(path)
                txt = f"'{p[2:]}'"
                print(txt)
                data = data.replace('__filename', txt)  # Assign the result back to data
                f.seek(0)
                f.write(data)
                f.truncate()
```

This is done in code for desktop clients. Mobile clients will continue to encode VP8 by default

- Based off 1.5.0, same as we were using before
- Remove optional dependencies
- Remove unnecessary dependencies

In addition, in this repo:
- Bundle the external plugins we are using as they are single JS files

* feat: Updates userRegion from backend.

* squash: Update comment.

* squash: Fix options.

* fix(codec) Debounce the call that calc codec intersection set.
Calculate codec intersection set only once per second even when there is a burst of joins/leaves. Also, check for current codec before chaining a codec change operation when codec selection API is used.

* squash: Address review comments

Jigasi / Jitsi (desktop) seems to encode apostrophes like (&apos or &#39) for
instance.

This is notably visible in the subtitles.

Normalize it so it's plain UTF-8.

Avoids having any actual remote audio tracks, which can mess with the
mobile audio session.

* feat(subject): Avoids setting subject if already set.

* squash: fix comments.

* squash: fix comments.
