Looking at the log on appveyor:

41.147 s: Semigroup 72: regular boolean mat monoid 4 using BMat8
0.128 s: Semigroup 73: regular boolean mat monoid 4 using BooleanMat

https://ci.appveyor.com/project/james-d-mitchell/libsemigroups/build/1.0.733/job/bhmf1wwpnhja3w04#L574

I wonder @flsmith whether in the soon to be added helper struct BMat whether if we detect that we're in a 32-bit system, then we ought to not use BMat8? What do you think?
