Input stream information on VU meter and spectrometer screens

[rpt]

I'd like to see the input stream type and resolution, for example "LPCM 48 kHz/24 bit" shown somewhere on the meters, just like it is shown on the "plain" active input screen. Now and then I'd love to see the stream type at a glance without swapping the screen settings back and forth.

Theoretically easy to implement as the information is already available and as a quite static UI element, shouldn't need too much extra processing power either.
