Using `NonEmpty` with custom containers

[ronnodas]

I want to use NonEmpty<C> for my own collection types C. Although I can implement some methods and traits on this, I don't see a way to construct an object of such a type. Any such constructor probably needs to be unsafe, since the whole point of the crate is to be able to add the non-empty guarantees. But maybe there's a good reason that the crate exposes separate from_vec_unchecked, from_hashset_unchecked etc instead of a single from_inner_unchecked for arbitrary inner types?

Of course I can have my own NonEmpty wrapper with the same semantics, but that seems redundant and awkward given that I'm already using mitsein.
