A library to provide data types for large (ie > 64 bits) but fixed width signed and unsigned integers with the usual typeclass instances to allow them to be used interchangeably with Word64.

The types and operations are coded to be as fast as possible using strictness annotations, INLINEABLE pragmas and unboxed values and operations where appropriate.
