New client supporting your dynamic OPML / reading list

[Alkarex]

Hello, Just FYI, one of your users recently requested the support of dynamic OPML / reading lists in FreshRSS (an open source news aggregator I am maintaining).

I have just implemented this ability to subscribe to a dynamic OPML such as yours https://github.com/FreshRSS/FreshRSS/pull/4407 and I thought some of you might be interested in giving it a try. I am looking for testers for this PR / feature :-)
