"invalid escape sequence `\|`" warning when running `verify.py -h`.

[serges147]

On latest python 3.12.2 (macOS 14.4) when running verify.py -h there is following warning in the output:

./build-tools/bin/verify.py -h
/Users/sergei/Develop/git/OpenCyphal/CETL/./build-tools/bin/verify.py:164: SyntaxWarning: invalid escape sequence '\|'
  """
...

It seems that "Cyphal" logo text "image" is missing "r" (raw string) prefix (like r"""...).
I'm gonna fix this as part of my onboarding (fork, pr, etc.)
