Add support for .lrc as is available via the web client

Describe the feature you'd like

Hi folks,
I searched for an issue for this before posting and was surprised not to find one.
The .lrc support for music was a tremendous step forward and I'm thoroughly enjoying it.
Unfortunately, it has yet to come to the Roku client and that's what I run in my house.
Hoping the port of this code would not be too much effort.

I opened this a while back but no feedback or support. #1901

I also would like support for .lrc files on Roku Jellyfin.
I enjoy looking at the lyrics while listening to the music which I can do through chrome login to the Jellyfin server on my laptop. This option is especially important for medleys.

Thanks for your hard work.
