This patch series contains a few improvements for the `diff archive` tool,
mainly based on Wolfgang's and Thomas' suggestions.

First, the output of is now much more detailed and shows
some relevant file attributes, including what has changed between
snapshots. Changed attributes are highlighted by a "*" and are
highlighted by colored text.

For instance:

$ proxmox-backup-debug diff archive ... --compare-content
A  f   644  10045  10000     0 B  2022-11-28 13:44:51  add.txt
M  f   644  10045  10000     6 B *2022-11-28 13:45:05 *content.txt
D  f   644  10045  10000     0 B  2022-11-28 13:17:09  deleted.txt
M  f   644  10045    *29     0 B  2022-11-28 13:16:20  gid.txt
M  f  *777  10045  10000     0 B  2022-11-28 13:42:47  mode.txt
M  f   644  10045  10000     0 B *2022-11-28 13:44:33  mtime.txt
M  f   644  10045  10000    *7 B *2022-11-28 13:44:59  size.txt
M  f   644 *64045  10000     0 B  2022-11-28 13:16:18  uid.txt
M *f   644  10045  10000    10 B  2022-11-28 13:44:59  type.txt

Furthermore, there now exists the possiblity to pass
the --compare-content flag to the tool. If the flag is passed,
the tool will compare the file content instead of relying on mtime
alone to detect modifications.

This patch series adds new dependencies to the `termcolor` and `atty`
crates. That being said, both crates were already pulled in
by other crates as transitive dependencies.


Changes from v1:
  - Made `changed indicator for file content` a bit less confusing.
    For regular files, it is now only displayed if
      - the --comapare-content flag is set and
      - the file contents *actually* differ

  - Removed unnecessesary namespace prefix for std::task::Pin in unit tests
  - Added color output, controllable via --color {always,auto,never} flag.


Lukas Wagner (3):
  debug cli: show more file attributes for `diff archive` command
