Subject: [PATCH] Make mimalloc optional

What?
=====

mimalloc significantly reduces execution time in local benchmarking, but
may be causing problems with ARM architectures (specifically the MBP
M1s).

This shifts mimalloc from a hard dependency to a feature flag which can
be configured during install.
