Playlist & group selection

[antebrl]

🚀 Description

Problem to solve

To filter the channels it should be possible to filter by playlist and filter by group!

Proposal

There should be a dropdown menu on All Channels, which lets you select a playlist. Playlists should therefore be provided with a name and should be stored in a hash-map server side.

Besides the playlist selection, there should be another dropdown menu for group selection. Default All Groups. One channel can only be assigned to one group, so the channel will hold a attribute group, which will filter accordingly.
