Option to show filesystem attributes

[pinusc]

Some filesystems allow the user to set filesystem attributes on files with chattr. These are not extended attributes, so calling exa -@ won't do anything.

These attributes are present in ext2/3/4 and other filesystems as well. I mainly use the +d attribute (nodump) to control which files tarsnap backs up; I can check if files have the +d attribute by checking the output of lsattr $file, but that's quite bothersome. Being able to see it in the output of exa would be much better.

Other attributes (from the Arch Wiki) are:
-a: append only
-c: compressed
-d: no dump
-e: extent format
-i: immutable
-j: data journalling
-s: secure deletion
-t: no tail-merging
-u: undeletable
-A: no atime updates
-C: no copy on write
-D: synchronous directory updates
-S: synchronous updates
-T: top of directory hierarchy

I understand that this is a niche feature; but then again, so is xattr listing!
