it is incomplete, basically I was fishing for a general OK to (ab)use
the dictionary in the MOVContext as a means to pass on the list of
keys, having done that, I've moved on to extend the data types
understood to include other data types (The sample ARRI clips need
signed and unsigned integers). I have this working but the code is in
need of a refactoring to say the least.

There does not appear to be a way to indicate the 'type' of data
pushed into the dictionary so that if I wanted to serialise it back
out I could get the same format, is this something people have

I could use a type dictionary to store the original type of the keys
along side the standard metatdata dictionary, but how that would feed
into the metatdata mux/demuxing and the command line interface I don't
