Increase Equihash parameters to n = 96, k = 3 (about 430 MiB)
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.

Use depth-first scan for eliminating partial solutions instead of breadth-first
This reduces the peak number of lists in-memory from 2^k to k, and enables the
solver to eliminate most duplicates before it has instantiated the full set of
leaves.
