Change hometeam_score from Number to String in schema.

The JSON response for matches that are yet to be played shows a '?' for the score. Given that this is mapped to a hometeam_score attribute in the schema, which was a number, it could not be parsed. For the time being I'll leave it as a string, but there's probably a better way to solve this - most likely on the processing side.

For matches that are yet to commence don't process the scores at all. Probably easiest with dates, but this is something to look at in the future.
