Create a class that implements the skewed associative placement
policy. It uses the hash function and expansions of the skewing
functions described in "Skewed-Associative caches", by Seznec.
Only 8 skewing functions are implemented, and therefore if more
are needed a hash function will be recursively applied on top
of the output of one of these functions to generate different
values. This is not optimal, and if more functions are needed
it might be more effective to implement them.
