Disable the disabling of the add-on on shadow roots

[gbesacier]

Describe the bug
I see that in #7 you added a check to disable ScrollAnywhere if a shadow root is detected. Apparently you did this because another addon was make a heavy use of shadow roots. The problem is that there are some legitimate non-addon use of shadow roots too, and I would like to use ScrollAnywhere with them. One example is the Home Assistant dashboard. Can you make this feature an option "enable/disable ScrollAnywhere on shadow roots"? Thanks

Steps To Reproduce
Steps to reproduce the behavior:

1. Open an Home Assistant dashboard, e.g. https://demo.home-assistant.io/
2. Scroll with the left button, it doesn't work
3. Open ScrollAnywhere.xpi and remove that part (!e.target || !e.target.openOrClosedShadowRoot)
4. Scroll with the left button, it works

Hello,
If I remember correctly, the main issue was that all clicks inside the shadow root are "hidden" from my code.
My code can see that user pressed a mouse button but, but not over which element.
And if you have a "left mouse button scrolling" enabled, my addon should start scrolling only if didn't clicked an input, button or bunch of other elements. Otherwise you won't be able to interact with anything inside the shadow root.

Although, I've tried to install the 8.3 version which doesn't have the fix and it seems to work fine... hmm.
Could try it too?
Click the "Download file" under the 8.3 version:
https://addons.mozilla.org/en-US/firefox/addon/scroll_anywhere/versions/
You can also disable updates for this addon in the "about:addons" page so it won't auto-upgrade.

I should be able to add a switch to enable it.
But I'm a bit far from the new release (I have a lot of work to do with my other addons currently...)

I tested a few cases (with the current version edited to remove (!e.target || !e.target.openOrClosedShadowRoot) and with unbranded Firefox to disable addon signature enforcement), and yes not everything works as it should

• stating the drag on a button and stopping the drag on the same button: scroll works but the button is clicked
• starting the drag on a button and stopping the drag outside the button: scroll works and the button is not clicked
• starting the drag on an empty area and stopping the drag inside a button: scroll works and the button is not clicked
• starting the drag inside a sub-element with its own scrolling (vertical or horizontal) : the main page scrolls instead of the sub-element

It still better than nothing.

But if at some point you can re-explore this issue, I know that there are some Home Assistant modules (written in javascript) that are doing some special things to be able to traverse through shadow roots. For example https://github.com/thomasloven/lovelace-card-mod?tab=readme-ov-file#dom-navigation
