Offer diskusage functionality in File-Manager

[PanderMusubi]

Functionality offered by https://github.com/IvanVolosyuk/diskusage is very useful for graphically finding files and directories that take up a lot of disk space and can be removed. See https://github.com/IvanVolosyuk/diskusage and https://f-droid.org/en/packages/com.google.android.diskusage/

Personally, I use it a lot. However, the maintenance of this app is minimal. Perhaps it is better to have File-Manager offer something similar. Especially deleting (trash can) and moving files could be handled by existing functionality.

Can you raise it as a feature request in File Manager? Thanks!
