    opr: Add Bob Jenkins's hash functions
    
    This imports a small subset of Bob Jenkins lookup3.c hash functions
    into the opr library. At present we only import the subset of this
    that deals with aligned arrays of integers, as this addresses our
    immediate need.
    
    It seems likely that if we're interested in a hash function for string
    arrays (or other arbitrary data), that more recent functions such like
    SpookyHash (from Bob Jenkins, again) or CityHash (from Google) may be
    a better solution.
    
    The immediate use case for this is removing the use of the '%' operator
    when indexing speed critical hash tables, as well as ensuring fairer
    distribution of entries across these tables.
    
    A short set of test cases is also provided
