Seems that instances in quickcheck-instances generate subseconds. Either we could use checkUrlPiece' or own equality.

EDIT went with first option, for know. quickcheck-instances generate subsecond times, which fail to roundtrip with this package atm

There was an issue on UUID before — #21. @gregwebs had some points to not have uuid dependency here.

[phadej]

bummer. uuid is an extremely light dependency.
So far it's 2-1 for having uuid (assuming @fizruk is 👍 and @gregwebs is 👎).

Continuing from #21, cuid is nice too, and it's instances could be here too, but when interoperating with java-world apps, not having UUIDs is no go.

[phadej]

FWIW, I'll redo this PR with depending only uuid-types which is indeed much lighter than uuid

EDIT done
