Deserialize Metrica Sports event data json format into a `EventDataset`.
Parameters
----------
inputs : dict
input `event_data` should point to a `Readable` object containing
the 'json' formatted event data. input `metadata` should point
to a `Readable` object containing the `xml` metadata file.
options : dict
Options for deserialization of the Metrica Sports event json file.
Possible options are `event_types` (list of event types) to specify
the event types that should be returned. Valid types: "shot", "pass",
"carry", "take_on" and "generic". Generic is everything other than
the first 4. Those events are barely parsed. This type of event can
be used to do the parsing yourself.
Every event has a 'raw_event' attribute which contains the original
dictionary.
Returns

dataset : EventDataset
Raises
