[IMP] l10n_au: tax report headings

- Remove "subtotal" amounts from headings.
- Pull GST only and G20 in under purchasing header.
- Remove tag from comparison heading, as it should have no links to audit.
- Add summary section, to make G9 and G20 transfer to 1A / 1B as per ATO
suggested formatting, and to make those figures easier to find on the
report.
