Ability to pause Melody IC 1270

**Is your feature request related to a problem? Please describe.**
When wanting to pause a song played with the MIDI player IC 1270 it starts again at the start of the song rather than the position you were at.

**Describe the solution you'd like**
A way to start playing again at the position that you stopped at. This might be done via a parameter on the sign (PAUSE) but that means there would need to be a reset too, alternatively a redstone input from the side of the sign could pause it instead.

**Describe alternatives you've considered**
Using a different plugin or splitting up midi files (which wouldn't allow to arbitrarily pause)

**Additional context**
None?
