To minimize delay to First Contentful Paint. The idea is to avoid
complex data structures such as Map in order to speed up first content
script execution. Use stringified arrays where practical and
instanciate those arrays from their stringified representation only
when there are actual cosmetic filters to apply.

The issue was fixed months ago.
The removed code block is causing uBOL to be flagged as "including
remotely hosted code".
To be clear, the removed obsolete code block was not related to
executing remote code. The referenced code was in the file itself,
not remote, and this was a workaround for when Firefox was not
supporting injecting script in the `MAIN` world.
The issue was fixed months ago in Firefox, so there is no point for
the workaround.
When the target world of a scriptlet is the ISOLATED one,
skip Blob-based injection in Firefox, as the current world
is always the ISOLATED one. This should make ISOLATED
world-based scriptlets more reliable (i.e. execute sooner)
in Firefox.
Additionally:
Use `export UBO_VERSION=local` at the console to build MV3 extension using
current version of uBO code base. By default, the version is taken from
`./platform/mv3/ubo-version' and usually set to last stable release.

Currently, there is no other way to inject CSS user styles than to
wake up the service worker, so that it can inject the CSS styles
itself using the `scripting.insertCSS()` method.
If ever the MV3 API supports injecting CSS user styles directly
from a content script, uBOL will be back to be fully declarative.
At this point the service worker is very lightweight since the
filtering is completely declarative, so this is not too much of
an issue performance-wise except for the fact that waking up the
service worker for the sole purpose of injecting CSS user styles
and nothing else introduces a pointless overhead.
Hopefully the MV3 API will mature to address such inefficiency.
