Discussion
----------

There is no denying that Java  EnumMap and EnumSet are fast. Given that JMH supposedly has
an over head of 2-3ns, they both offer roughly 2-3ns/op, which might just be noise !

On the other hand, plain old Scala Set and Map aren't bad either, coming in at < 10ns/op,
which is maybe 4-6ns/op accounting for overhead and noise.

So the current state of things is that Java EnumMap and EnumSet are roughly 2x faster than
plain old Scala Set and Maps w/ Enumeratum, but being that we're still in the sub-10ns
range, it seems reasonable to say that performance here won't be a bottleneck except in super
edge cases.
