SyntaxWarning: invalid escape sequence '\m' in doc string

[juntyr]

Loading the xrft package v1.0.1 produces the following warnings on Python 3.12:

/lib/python3.12/site-packages/xrft/xrft.py:284: SyntaxWarning: invalid escape sequence '\m'
  """
/lib/python3.12/site-packages/xrft/xrft.py:491: SyntaxWarning: invalid escape sequence '\m'
  """
/lib/python3.12/site-packages/xrft/xrft.py:691: SyntaxWarning: invalid escape sequence '\o'
  """
/lib/python3.12/site-packages/xrft/xrft.py:796: SyntaxWarning: invalid escape sequence '\o'
  """
/lib/python3.12/site-packages/xrft/xrft.py:902: SyntaxWarning: invalid escape sequence '\o'
  """
/lib/python3.12/site-packages/xrft/xrft.py:1012: SyntaxWarning: invalid escape sequence '\s'
  """
/lib/python3.12/site-packages/xrft/xrft.py:1088: SyntaxWarning: invalid escape sequence '\s'
  """
/lib/python3.12/site-packages/xrft/xrft.py:1174: SyntaxWarning: invalid escape sequence '\s'
  """

The corresponding doc strings should use raw string literals (r""" ... """) since they contain invalid escape sequences (I think for LaTeX content).

Thanks for your help!
