v1.522: noise blanker/filter improvements
From the CHANGE_LOG file:
v1.521,522 May 8, 2022
Improvements to noise blanker/filter operation. All settings now saved in browser storage and
recalled on page load. All settings can have default values setup by the Kiwi admin. This could
be used to mitigate known, constant noise sources so for example the blanker is automatically
active when first-time users connect.
A new "default" button at the top of the extension panels cab be used to load the defaults.
To simplify setting up the defaults the admin can use a new right-click menu entry
"Save noise defaults" which copies the current settings into the Kiwi configuration.
Admin password may be required (e.g. if not on the local network).
Made photo uploads work again (admin page, webpage tab).
