SyntaxWarning with Python 3.12

[elboulangero]

With Python 3.12:

/usr/share/unicorn-magic/unicorn.py:1241: SyntaxWarning: invalid escape sequence '\.'
  elif re.search('\.ps1$', sys.argv[1]) is not None:

This change is documented at https://docs.python.org/3/whatsnew/3.12.html#other-language-changes:

A backslash-character pair that is not a valid escape sequence now generates a SyntaxWarning, instead of DeprecationWarning. For example, re.compile("\d+.\d+") now emits a SyntaxWarning ("\d" is an invalid escape sequence, use raw strings for regular expression: re.compile(r"\d+.\d+")). In a future Python version, SyntaxError will eventually be raised, instead of SyntaxWarning.

Patch (trivial):
