Field_config refactored

[mavaylon1]

Motivation

What was the reasoning behind this change? Please explain the changes briefly.

1. We want to use the PyNWB typemap when using the TypeConfigurator in pynwb. As a result we need to update the field setter to take in typemap.
2. I cleaned up the field_config method.

We can override the get type map function on the pynwb side.
