Continuation of #1319.

Replaces generic-array with hybrid-array, which is built on a combination of typenum and const generics, providing a degree of interoperability between the two systems.

hybrid-array is designed to be a largely drop-in replacement, and the number of changes required to switch are relatively minimal aside from some idiosyncrasies.

@newpavlov well, there's the next step

Replaces `generic-array` with `hybrid-array`, which is built on a
combination of `typenum` and const generics, providing a degree of
interoperability between the two systems.

`hybrid-array` is designed to be a largely drop-in replacement, and the
number of changes required to switch are relatively minimal aside from
some idiosyncrasies.

Maybe we should move this method into hybrid-array? I think we had a recent discussion about it.

Sure, although perhaps that could be a followup?
