Reduce overhead of multi-type-ness (last Summer's SoC):

	Use uint32_t instead of size_t counts (halves size of ChanCount on 64-bit).
	Shift DataType values down to eliminate subtraction every index of a ChanCount or *Set.

Allow using DataType directly as an array index (prettier/terser).
Fix some mixed spaces/tabs in file comment headers.
