Add integration with 'tasty'

[chshersh]

I would really appreciate integration of this amazing type-spec library with tasty testing framework. From this issue I discovered that somebody needs to implement tasty provider as a third-party package (probably called tasty-type-spec).

Currently it's not convenient enough to use tasty alongside with type-spec. You can see how awkward integration can be in this example:

• https://github.com/serokell/o-clock/blob/ee092f3d344a4cfe1f23e2d0ee99a2f2331f6721/test/Test/Time/TypeSpec.hs

Using tasty-discovery can really help a lot this test-suite!

Maybe you're interested in implementing this integration or at least in having it?

Yeah, thanks for the interest. I will look into this, though I have no clue about tasty..(yet)
