Adding filter by URL that leads to file download

Hello,

I open [this](https://energized.pro/) page to add a third-party custom filter subscription. On the page, I scroll-down to the 'Ultimate' section and expand that to see all the relevant options as seen [here](https://prnt.sc/qCZrQpWvSu_5)

As seen in the screenshot, I click on the 'copy' link icon to copy the URL of the filter.

Now, I open AdGuard Chrome Extension options and navigate to Filters > Custom and when I try to add a custom filter by pasting the URL that I had copied, I get [this](https://prnt.sc/c1j2jeT21Mgi) error.

This is due to the fact that the website offers the URL to the filter as a downloadable file:

https://block.energized.pro/ultimate/formats/filter

I found a workaround to this. That is, to download the filter on my PC and then add the filter subscription by providing the path to the filter. However, I would like AdGuard to be able to add the filter when we directly provide the URL to a file too.

When I try to add the same filter in uBlock Origin extension, I am able to add it directly from the URL as seen [here](https://prnt.sc/FaXRTnW79JBI) and [here](https://prnt.sc/J-rI2Y2H7k7k).

I am therefore raising this request for you to add an enhancement to the Extension and other products for Android/Windows/etc. so that we are able to add the custom filter subscription URL directly.

Thanks!
