Example usage:
...##+js(trusted-trusted-click-element, #cmpwrapper >>> .cmpboxbtnyes)
The substring before ` >>> ` must select an element with a non-null
shadow root, in which case the substring after ` >>> ` will be used
to find the element in the targeted shadow root. ` >>> ` can be used
recursively when multiple shadow root must be pierced.

Improvements:
Support fulfilling the response with the content of a
`web_accessible_resources` resource, using the syntax already
supported by `prevent-xhr`: `war:[name of resource]`
Support fulfilling the response with randomized text with length
specified using `length:min[-max]` directive.

The benefits of diff-patching filter lists is much shorter update
schedule and significantly less bandwidth consumed.
At the moment, only default filter lists are subject to be
diff-patched.
External filter lists can make their lists diff-patchable by
following the specification link above.
Only filter lists fetched by the auto-updater are candidate for
diff-patching.
Forcing a manual update of the filter lists will prevent the
diff-patcher from kicking in until one or more lists are
auto-updated.
Some back-of-the-envelop calculations regarding the load on free
CDN solutions used by uBO to distribute its own filter lists:
Currently, for each CDN (with lists updating after days):
~560 M req/month, ~78 TB/month
With diff-patching lists on a 6-hour schedule:
~390 M req/month, 1 TB/month
Those estimates were done according to statistics shown by
jsDelivr, which is one of 4 CDNs picked randomly when a list
updates:

Essentially a complement of `trusted-prune-inbound-object.js` added in
1c9da227d7
To perform object pruning on any object returned synchronously by
any given call.
The arguments for `trusted-prune-outbound-object` in order are:
- The name of the property to trap. Must be a function, and must
exist when the scriptlet tries to install the trap.
- The properties to prune (as with `json-prune`)
- The properties which must all be present for pruning to occur
(as with `json-prune`)
The scriptlets `json-prune.js` and `evaldata-prune.js` essentially
perform the same function, and will eventually be rewritten to
internally delegate to generic `trusted-prune-outbound-object.js`.
As per discussion with filter list maintainers.
To perform object pruning for any given call which has an object
as argument (hence "inbound").
Since `json-prune-stringify` scriptlet is a specific form of
pruning inbound objects, it has been removed.
The arguments for `trusted-prune-inbound-object` in order are:
- The name of the property to trap. Must be a function, and must
exist when the scriptlet tries to install the trap.
- The position of the object to prune in the argument list when
the trapped function is called. The position is 1-based and
must be an integer greater than 0.
- The properties to prune (as with `json-prune`)
- The properties which must all be present for pruning to occur
(as with `json-prune`)
- Varargs:
- `, dontOverwrite, 1`: do not modify the target inbound object
Examples:
Remove `title` and `name` properties before passing the object to
`JSON.stringify` call:
example.org##+js(trusted-prune-inbound-object, JSON.stringify, 1, title name)
Remove `status` property before passing the object to `Object.keys`
call but do not modify caller's instance of the object:
example.org##+js(trusted-prune-inbound-object, Object.keys, 1, status, , dontOverwrite, 1)
