Backport features from strudel

[yaxu]

While porting Tidal to Strudel, some things have been improved, like more ways of combining patterns. In particular:

• reset/restart operators - would fix #785
• an extended family of pattern composing operators https://github.com/tidalcycles/strudel/pull/88#issuecomment-1114036935
• Tidier implementations of some core functions, like chop

It'd be good to backport some of this

Currently:

strudel	tidal
.addIn	`
.addOut	`+
.addMix	`

Ideas for the new operators:

strudel	tidal
.addSqueeze	||+
.addSqueezeOut	+||
.addTrig	!+
.addTrigzero	!!+

Squeeze: https://github.com/tidalcycles/Tidal/commit/a7ff6d08bb8650d0ade71bcb1c3fa4651c1e4481

Really cool! It's possible to document the new operators?

This is basically implemented in the cycseq branch, although not working yet so not ready for documenting.
