Create a new script to fix MD5 signature missing in FLAC files.

For example, the FLAC files provided by Qobuz used to have a MD5
signature, but currently they don't have one anymore.

To add the MD5 signature, it is necessary to reencode the files. The
operation could be done with a single flac command, but I'd rather
split it into two steps (decode to .wav and then reencode to .flac).

In addition to lsblk command, also call udevadm on devices to retrieve

In the first place, I wanted to print the USB version (USB 2.0,

specifications that it is clearer to just print the speed itself.
Moreover, the speed information is not concerning only USB devices.

Sometimes a file may have been moved from a directory to another one,
or just renamed. It results in a file being removed and another one
being added.

Print the checksum of removed and added files, so that we can compare
and verify that the checksum has not changed in that case.

The script itself cannot detect that a file was moved or renamed, this
would involve too much processing.

NB: If the file was moved to a new directory, the checksum will not be
printed.

Fedora distribution used to follow User Private Group (UPG) scheme, but
it seems not to apply anymore. With Fedora 38 (and maybe earlier
versions), the umask in a terminal is now 0022.

Moreover, even when UPG scheme applied, the behaviours of the different
applications were not consistent. The umask was 0002 in the terminal,
but it was 0022 in XFCE Thunar (when creating a directory), in Firefox
(when downloading a file) and in Emacs (when creating a file)...

As a consequence, stop using UPG in mychmodro and mychmodrw, and don't
give write access to the group.

NB: Only these scripts are concerned. Continue not to override the
default umask in bash init.

The "create" command is renamed to "update", and is now able to update
an existing checksum file, if the content of the directory has changed.
If not already present, the checksum file is created like before.

An update is done in the following cases:
* If a file that is already listed in the checksum file was modified
  after the checksum file was created, then its checksum will be
  updated. (It is based on the last modification date.)
* If a file that is listed in the checksum file is no longer present,
  then it will be removed from the checksum file.
* If a file is not listed in the checksum file, then it will be added.

NB: The "update" command doesn't check the checksums. A bad checksum
will never be "fixed", unless the file was updated and requires its
checksum to be computed again.

Simplify the script by using a single function (process_dir) for all
commands. Most of the checks (to verify whether the checksum file is
up-to-date or not) are necessary in all cases, even for the "create"
command, which does not overwrite the checksum file anymore if it is
already present.

In case of directory content mismatch, don't print the two lists, this
is too much verbose.

When printing information, use bold green color only if an action has
been done on checksums ("done" when created, "OK" when checked).
Otherwise, when just mentioning that the directory content matches
("All files are listed"), use green color (not bold) instead.

Remove unused option_verbose variable.

When cleaning files, the number of "saved" bytes is printed, because
usually some metadata are removed (picture, comments...).

But in some cases, when adding information, the size of files can
increase, and a negative value of "saved" bytes is printed.

Instead, we should just print the difference of size, and a negative
value means that bytes are saved.

Sometimes you just want to check that all checksums have been computed,
but you don't need to really check them (It takes too much time and
requires to read the entire files from the disk to compute the SHA256).

With the new "list" command, the same verifications as with the "check"
command will be performed, but the checksums are not checked in the
end. These verifications consist in checking that the checksums.sha256
file:
- is present,
- is the more recent one,
- lists the exact content of the directory.
