Module compute

Compute kernels on top of Vortex Arrays.

We aim to provide a basic set of compute kernels that can be used to efficiently index, slice, and filter Vortex Arrays in their encoded forms.

Every array encoding has the ability to implement their own efficient implementations of these operators, else we will decode, and perform the equivalent operator from Arrow.
