Bincompat issues because of dependency on shapeless 2.3.6

See original GitHub issue

Shapeless 2.3.6 introduced a bincompat issue described here: https://github.com/milessabin/shapeless/pull/1158#issuecomment-838071648

The following release 2.3.7 fixed it via https://github.com/milessabin/shapeless/pull/1162

Circe 0.14 depends on shapeless 2.3.6.

Having shapeless 2.3.7 in classpath leads to a compiletime error:

[error] Symbol 'type shapeless.ops.function.FnFromProduct.Aux' is missing from the classpath.
[error] This symbol is required by 'value io.circe.generic.decoding.IncompleteDerivedDecoders.ffp'.

circe-generic can’t work with shapeless 2.3.7+

FTR that’s not exactly a binary compatibility issue. It’s pickling issue, meaning that either it will:

Not compile when mismatching versions of Tupler, FnFromProduct or FnToProduct are used
Compile and work fine at runtime (since the type aliases are erased)

I couldn’t find any usage of those in refined so it should be fine either way.
