[FEATURE]: Display stream id in mux list for multistreams

[deeptho]

Description

The display of multistreams in the muxes list is confusing: the stream id is not shown, so the user sees multiple muxes with all the same parameters, but cannot tell which entry is for which stream without clicking on the entry and checking the parameter entry window,

Help and Guidance

The implementation is simple. I will create a pull request.

Acceptance

• [x] The proposal will be developed and maintained by me

Is anything more needed to prepare this patch for inclusion in tvheadend?

Closing as the PR was abandoned.
