HyphaeVM - WIP

This commit is a WORK IN PROGRESS for the base implementation of the
HyphaeVM. This will be squashed into a larger commit eventually when
the work of implementing the HyphaeVM is finished.

Of note, the ISA is mostly finished and much of the VM design is in
place. Yet to be done are a few traps in mycelium, migrating pieces
like the number package and the sexpr package into the VM package,
and of course much testing.
