commit 0dfbea437a0875516a472f70c896caf5a5868d75

    Handle deserialization of tuples, etc specifically
    
    Previously BinIface would build a UniqFM containing all of the known-key
    things and use this to resolve the Names of known-key things during
    interface file deserialization. However, this has the disadvantage of
    building up a rather large map containing all type and data constructors
    for anonymous sums and tuples.
    
    We now instead add codepaths to map a unique back to its associated
    known key name, allowing us to greatly shrink the size of the map.
