Add streamlink-twitch-gui, Twire, Xtra, ElectronPlayer for Twitch

[Mennaruuk]

streamlink-twitch-gui: Requires login, but it works very well, streams via streamlink to VLC

Twire: Twitch client for Android, supports VODs with chat replay, custom emotes (BTTV and FFZ) and Picture in Picture mode

• Twire seems to require log in to work, a limitation of Twitch's new API called Helix.

Xtra: Twitch player for Android

I tried ElectronPlayer. It has the same concept as the wrappers for YouTube. So it's essentially a browser wrapper around Twitch.com that blocks ads among other features. Also, it only supports Linux and macOS at the moment, with the Linux version last released in February 2020.
