Display multimedia messages: audio, video, stickers (gifs)

[kevinaboos]

Currently Robrix supports displaying text messages and static (non-moving/animated) image messages.

The Matrix spec supports multiple other kinds of multimedia messages, as defined here by the MessageType enum. This issue is primarily concerned with:

• Audio: the AudioMessageEventContent type
• Video: the VideoMessageEventContent.
• Animated images/gifs for Image/Stickers: the StickerEventContent type
  • This is separate from the other MessageType variants
  • We support static image stickers.
    Currently, this is blocked on Makepad adding support for video and audio playback. @joulei is currently working on it.

Since i have handling the related code about image message in timeline for a time, i would love to fix this issue.

I would focus on audio/video till Animated images/gifs is not blocked.
