Currently the source slice must be the exact length to fill the array to max capacity, this is an unnecessary restriction since an `ArrayVec` is a variable sized data structure. Set the destination slice to be the same length as the source slice (still maintain capacity checks).
Test that we can extend an `ArrayVec` with a slice that is less than remaining capacity.
