Slice is straightforward to do because it is fixed consts.
*please do not use SimdSwizzle* it is too massive a jump
and throws away far too much code.

once Slice is done Part is (error checking aside) literally
1 line of code, using existing Simd shift operator and using
straight slices:

    return (self >> offset)[:width]

that's it.  incredibly simple.

yes agreed under no circumstances do we go anywhere near LHS Part
right now.
