List all block groups/chunks
New command has been added in v6.1 to list all block groups/chunks. Not yet finalized.
Example output:

Remaining work:
- test on mult-device filesystems, the grouping is wrong in combination with --sort
- finish the sorting infrastructure (to allow multiple keys and direction), replace current sorting keys
Now available in the experimental build, sorting a few columns work, multi device works (device id is printed in the column).
Remaining: reorder columns

Documentation updated. I'll move it out of experimental in 6.10 and then reorder the columns after feedback. Eventually the list of columns can be also specified e.g. like the util-linux tools do.
