Django-plausible-proxy

- Made it possible to proxy script names with combined extensions

- Drop support for Python 3.7.
- Make it possible to call send_custom_event() with explicit remote_addr.
- Make it possible to render the {% plausible %} templatetag without the request object, when PLAUSIBLE_DOMAIN is set
in settings. Thanks hendi for the report. Ref 7.

- Added support for Python 3.11.
- Set timeout for upstream requests and added PLAUSIBLE_REQUEST_TIMEOUT settings option to override it. Thanks yoshson for the contribution. PR 5.

- Added PLAUSIBLE_SCRIPT_PREFIX to make it possible override default location of the proxy script (`js/script.js` -> `${PLAUSIBLE_SCRIPT_PREFIX}/script.js`). Thanks aareman for the suggestion. Ref 2.

- Added PLAUSIBLE_BASE_URL settings option to make it possible to use the project with self-hosted Plausible installations. The default value is https://plausible.io (use the cloud version.) Thanks aareman for the contribution. PR #1.
- Made PLAUSIBLE_DOMAIN settings optional. If the value is not set, the domain name is taken from the request.
- Added more tests.

- Fixed app config
