Fix Rand.u8() to return unsigned integers
...
Existing test vector generators are adjusted to use Rand.i8() so they
generate the same test vectors. We should evaluate these later to
determine whether they should actually use Rand.u8() (and update the
test vectors across the ecosystem).

Split apart MapToCurveSimpleSWU and GroupHash test vectors
...
The test vector generators in this repository are meant to output data
that can be copy-pasted or piped to a file. Generating multiple sets of
test vectors from a single file interferes with this.
