This is a generalization of deinterleave_groups_shuffle for n wides.

The different name comes from for 2 wides - this returns a tuple of 2 wides and a shuffle returns an aggregate

First parameter is fixed<N> group_size - how many elements we consider one element After that you pass n simd values. Together those n simd values have interleaved values. We return a tuple of wides, where all values are separated between individual wides.

NOTE: you can think of this function as AoS to SoA, where all fields have the same size. group is the size of the field in wide elements.

Examples (one letter is a group - first parameter, group order is preserved): ABAB'ABAB ABAB'ABAB => [AAAA'AAAA BBBB'BBBB] ABCA BCAB CABC => [AAAA BBBB CCCC] ABCD'EABC DEAB'CDEA BCDE'ABCD EABC'DEA BCDE'ABCD => [Ax8 Bx8 Cx8 Dx8 Ex8]
