duncantl/RDAInfo: Read summary of RDA files and restore individual elements

This reads RDA (version 3, XDR format) files to get the names, types, lengths and positions/(offsets in the stream) of the top-level variables it contains. It does this without reading/deserializing the actual values. It can also deserialize individual values. Both of these make it useful when dealing with very large Rda files, especially if we only want to find the names of the variables they contain, or want only a few objects from it. While written in R, for large Rda files, it is faster for answering certain questions that do not require restoring all the objects which is the only option the existing Rda deserialization code offers. It also provides an R implementation of the C code in serialize.c in the R source with which people can experiement, specifically extensions to the format.
