gmbecker/fastdigest: Fast, low memory footprint digests of R objects

Provides an R interface to Bob Jenkin's streaming, non-cryptographic 'SpookyHash' hash algorithm for use in digest-based comparisons of R objects. fastdigest plugs directly into R's internal serialization machinery, allowing digests of all R objects the serialize() function supports, including reference-stye objects via custom hooks. Speed is high and scales linearly by object size; memory usage is constant and negligable.
