Package bytesx implements highly optimized byte functions which extends the bytes package in the standard library (Currently x86 64-bit only)

EqualThreshold returns true if b does not differ in value more than t from the corresponding byte in a. t may take any value from 0 to 255 where 0 is exact match and 255 will match any string. If t is 1 and a is "MNO" and b is "LNP" than EqualThreshold will return true while it will return false if b is "LNQ" or "KNO". The equality check is only made untill the shortest of a and b.

IndexNotEqual returns the index of the first non matching byte between a and b, or -1 if a and b are equal untill the shortest of the two.
