Add dynseq to plugins list

[101arrowz]

Adds higlass-dynseq to the list of plugin tracks.

Side note: should the plugin data fetcher developed alongside this track (higlass-multi-tileset) be added as well?

Thanks for the PR! Happy to merge this but I think the description and image could be optimized a bit. Do you want to address this first?

[flekschas]

Just a suggestion but I would trim the image to be closer in its aspect ratio to the container's aspect ratio: https://higlass.io/plugins

Otherwise it's hard too see properly.

Could this be left as is for now and updated later? The sequence plugin does the same thing.

I wonder if it could be helpful to add the multi-tileset data fetcher plugin here as well. @pkerpedjiev What do you think? Since the page is just called Plugins I think plugin data fetchers would fit here as well.

Yes, definitely!
