MAXO annotation extraction transform script

[caufieldjh]

Extraction of MAXO annotations is helpful but would be much more helpful if we get the output in a format compatible with the other MAXO annotations, as seen here: https://github.com/monarch-initiative/maxo-annotations/blob/master/annotations/maxo-annotations.tsv

Or, if there's another desired format (JSON?) then we may convert to that, instead.
