Update MediaMTX

[mrlt8]

Update MediaMTX which offers an updated authentication system for streams and recording.

NEW: STREAM_AUTH option to specify multiple users and paths:

• Username and password should be separated by a :
• An additional : can be used to specify the allowed IP address for the user.
  • This does NOT work with docker desktop
  • Specify multiple IPs using a comma
• Use the @ to specify paths accessible to the user.
  • Paths are optional for each user.
  • Multiple paths can be specified by using a comma. If none are provided, the user will have access to all paths/streams
• Multiple users can be specified by using | as a separator

EXAMPLES:

STREAM_AUTH=user:pass@cam-1,other-cam|second-user:password@just-one-cam|user3:pass

• user:pass has access to cam-1 and other-cam
• second-user:password has access to just-one-cam
• user3:pass has access to all paths/cameras

STREAM_AUTH= user:pass:192.168.0.7|::192.168.0.10|::192.168.0.15,192.168.0.20@just-one-cam

• user:pass has access to all paths/cameras when streaming from 192.168.0.7
• No authentication required for all paths/cameras when streaming from 192.168.0.10
• No authentication required for just-one-cam when streaming from 192.168.0.15 or from 192.168.0.20

STREAM_AUTH=user:pass|:@public-cam|::192.168.0.17

• user:pass has access to all paths/cameras
• No authentication required for public-cam
• No authentication required for all paths/cameras when streaming from 192.168.0.17
