unit "s" unexpected behavior

[jqueraltmo]

speed 2 # unit "s" should slow down playback of the sample so that it would sound lower in pitch, and last two seconds, but it's clearly not doing this. See https://club.tidalcycles.org/t/unit-s-unexpected-behavior/4347

Thanks!

The current implementation is as follows:

• "r": changes sustain
• "c": changes sustain and speed
• "s": changes sustain

All this applies only to samples and is overridden by legato.

Once it has been decided by the community what they all should do, we can implement them.
