Title: added woocommerce_rate_label filter

added the filter 'woocommerce_rate_label' to better integrate 3rd party tax/address lookup to replace the rate with synced values instead of adding to the $rates array as the state may change and it is not reasonable to request a full array, by address and ZIP+4 for all nexus. This allows a single call to the remote API.
