Basins: Show list of basins in Analysis view

[B-Hartmann]

Shape-Out 2.19.1

What features are Basin mapping x?

Would it make sense to write in the tab Meta in Analysis View if a file contains basins so that users have a way of checking if the file is just small or contains basins and maybe where the remote file should be so that the basins work?

These features define which indices in the basin correspond to the current index: https://dclab.readthedocs.io/en/stable/sec_av_basins/index.html#definitions

IMO adding a tab in analysis view that lists all basins makes a lot of sense.
