Experiment: convert any CE effect type to a bifunctor effect

Seems to be working: cats-effect laws pass, but there may still be problems they don't reveal

Would it be possible to generalize this even further?

Namely, given any monofunctor F[_] and a corresponding cats type class instance e.g. cats.Applicative[F], generate the respective BIO type class instance [+E, +A] => izumi.functional.bio.Applicative2[Bifunctorized[F, E, A]] for it.

Repeat that for all conversions in izumi.functional.bio.CatsConversions, just the other way around

Sure, just need to make sure it's sound first.

Great to see this is still being worked on, thanks!

While this was being worked on, I have created my own two conversions I needed in the meantime, not sure if they are completely sound though, in case anyone needs: https://bitbucket.org/mucaho/ceffbanx/src/8986109fb7e9e97c7ae5a71ba311ff9d915634b8/src/main/scala/org/bitbucket/mucaho/ceffbanx/Util.scala#lines-130:180
