v0.4.0
Every tax group the official NF-e leiaute defines: 21 ICMS groups (was 5), PIS/COFINS by quantity, PISST, COFINSST, and the IPI stamp fields.
The tax payload now goes out in snake_case, matching the rest of the API. The XSD spelling is still accepted server-side, so existing code keeps working.
