------------------
* Fixed SQL Injection vulnerability, CVE-2021-30459. The toolbar now
calculates a signature on all fields for the SQL select, explain,
and analyze forms.
* Changed ``djdt.cookie.set()`` to set ``sameSite=Lax`` by default if
callers do not provide a value.
* Added ``PRETTIFY_SQL`` configuration option to support controlling
SQL token grouping. By default it's set to True. When set to False,
a performance improvement can be seen by the SQL panel.
* Added a JavaScript event when a panel loads of the format
``djdt.panel.[PanelId]`` where PanelId is the ``panel_id`` property
of the panel's Python class. Listening for this event corrects the bug
in the Timer Panel in which it didn't insert the browser timings
after switching requests in the History Panel.
* Fixed issue with the toolbar expecting URL paths to start with
``/__debug__/`` while the documentation indicates it's not required.
