Allow size 0 (void) components. These can be used as flags allowing to iterate over entities with certain flags, but without the need to branch on the value of a bool/bitset, ~~but there is an extra branch in the get/set functions~~ the new branch in get/set should be comptime evaluated and not impose any overhead at runtime. This also doesn't add any per-entity storage overhead, but does add the overhead of new archetypes for each combination of void-components used.
