[Python] add a field() method to StructType that returns the user a field

[asfimport]

Joris suggested here "we could also add a field() method that returns you a field? (that is more discoverable than {}[]{}, and would be consistent with a Schema and with StructArray (to get the child array for that field)".

 

Completion of this issue would also mean updating the example in the API docs for StructType to mention .field().
