Shrink Slice memory usage by turning most enums into bytes

Unfortunately Enum is 4 bytes (32-bit) or 8 byte (64-bit).

Also replaced TargResidue's 64-bit floats with 32-bit ones, which is still excessive, 16-bit fixed-point would be plenty.

Reduces sizeof(Slice):
32-bit: 248 -> 216
64-bit: 376 -> 296 !!
