Filter Keyword in API returns only exact match and not partial match #80

Expected behavior

products = api.Products.all(name='toy')
Should yield all products with the keyword 'toys' in the title as per "Filters can be applied to all methods as keyword arguments"
https://pypi.org/project/bigcommerce/

Actual behavior

I only get results when the keyword filter is an exact match, rather than a partial match.

Steps to reproduce behavior

products = api.Products.all(name='toy')
