add pickF and pickmodF

[geikha]

Allows to pick functions via a pattern of numbers, to apply to another pattern.

Example:

note("<c2 d2>(3,8)").s("square")
    .pickF("<0 2> 1", [jux(rev),fast(2),x=>x.lpf(800)])

I don't understand what's failing here. The examples work perfectly when I run them on the REPL!

yep that's normal, the examples are automatically tested with snapshot testing. snapshots for new examples need to be generated by running pnpm snapshot. then push the updated .snap file and everything should be fine
