[bug] e2ee encryption on linux is broken due to dataPacketCryptor exception

[robbysneller]

Describe the bug

When creating a room with e2ee enabled on linux, you will get an exception of Exception: createDataPacketCryptor failed: MissingPluginException(No implementation found for method createDataPacketCryptor on channel FlutterWebRTC.Method)

It appears that in the setup function of the e2ee manager for a room, the _dataPacketCryptor is attempted to be created like so

_dataPacketCryptor ??= await dataPacketCryptorFactory.createDataPacketCryptor( algorithm: _algorithm, keyProvider: _keyProvider.keyProvider);

however, from what I can tell, this is not implemented in flutter-webrtc. I have created an issue to document this, (flutter-webrtc/flutter-webrtc#2010) but I think that the room should still be setup with the audio/video encryption on linux rather than crashing entirely, which effectively makes it so that e2ee is NOT functional on linux from what I can tell.

I added a try catch around this function call in the e2ee setup, and was able to join the call with encryption enabled.

To Reproduce

try and join a call on linux with e2ee enabled and provided to the room

Expected behavior

the call is joined with encryption enabled
