std.hash.crc: simplify api

Browse Source 
This removes the two original implementations in favour of the single
generic one based on the Algorithm type. Previously we had three, very
similar implementations which was somewhat confusing when knowing what
one should actually be used.

The previous polynomials all have equivalent variants available when
using the Algorithm type.
