Title: Return useful values: only 64 bits at a time, and as UVs when possible

Returning ASCII strings of big numbers is silly if UV is big enough to hold them. So use UVs when possible.

Returning one big ASCII string for the 128-bit hash is silly since it's actually two 64-bit numbers. Return them separately as a list.

Also, for both 64- and 128-bit versions, provide functions that return the numbers as packed strings, for use on smaller architectures or when packed strings are more useful (e.g. building other strings).
