Changes:
- floor(512/n)*n/8 bytes of BLAKE2b output is split between floor(512/n)
adjacent indices, instead of using one hash call per index.
- Parameters with n/(k+1) mod 8 != 0 will expand the BLAKE2b output to byte
boundaries for colliding, instead of using a longer output and clearing bits.
- The genesis blocks have been regenerated.
- The test vectors have been regenerated.
- The Equihash inputs for the cancellation tests were modified to ensure that
valid solutions were available to exercise the full solver.
This version works, but generates the initial rows in a way that is not what we
want to specify. See #1175 for resolving this.

Includes a tweak to set the fixed-width of the rows based on whether the first
or last round is widest. This is necessary for some parameters, these ones
included.
