Add option to disable kind projector

[kubukoz]

Hi! It'd be nice to have an easy way to disable kind-projector, e.g. for builds of other compiler plugins (so that they can be built for a Scala version KP doesn't support).

Would be good to have a setting for better-monadic-for as well.

[kubukoz]

Yeah. I'm kind of amazed that it still works for all 2.13 versions, given that it's not cross-compiled for patch releases.

Hmm.. If I'm not mistaken, it became a compiler option in Scala 3, didn't it?

[kubukoz]

Yes... but we're still getting new 2.x versions.

Right.. I'm just thinking about integration with scalac-options and how to address such differences..

Right, that's gnarly. That's the kind of thing that has to be resolved in sbt-typeleve-settings I think, since scalac-options can't really do anything in this area for Scala 2.
