1.10 - July 31st 2023

This is the last release before a huge refactorisation that will break
everything. So consider it as the last "stable" release for a while.
This is mostly a bugfix release.
- IMPORTANT : new optional dependency : python-chardet
- IMPORTANT : Gopher directory index filename changed from "index.txt" to "gophermap". To update the cache to the new format run the `migrate-offpunk-cache` script (Sotiris Papatheodorou)
- "set accept_bad_ssl_certificates True" now also used for Gemini expired certificates
- Add missing chardet module (Sotiris Papatheodorou)
- Fix merging dictionaries with common keys (Sotiris Papatheodorou)
- Fix Gopher requests (rewrite URL parsing code per RFC 4266)
