Allow Scala 3 update

[regadas]

This is merely an evaluation of the new setting coming up in sbt 1.7.0 and the new compiler flag in scala 3.1.2 that allows setting the output target.

@johnynek Since this relies on a milestone version not sure if you wanna go for it.

Fixes #285
Closes #408

FYI, it seems the Scala 3 team has decided to go in another direction. The new compiler flag has been removed from Scala 3.2.0.

I guess we should wait until the next version of cats which gets scala native and I think may push us up to 3.1 publishing anyway.

@johnynek Yup that makes sense! I'll close this not this was some exploratory stuff anyway. 😄 Thx
