[Streams] Trovo support

[Zephyrkul]

Description of the changes

Adds Trovo support to Streams.

Have the changes in this PR been tested?

Sort of. The code itself has been tested over the course of a few months. The new method of obtaining a Trovo client ID has not been tested, as I first obtained mine via an old method that's no longer used. Some basic instructions are provided from what I could figure out, but there may be inaccuracies or it may be missing some steps.
