SyntaxWarning when using -x option

[artkos]

I get syntax warning:
/usr/bin/opensips-cli -x mi get_statistics all
/usr/lib/python3/dist-packages/opensipscli/modules/mi.py:87: SyntaxWarning: invalid escape sequence '.'
m = re.match('([a-zA-Z.-_]+)=', p)

#python3 -V
Python 3.12.3

I fixed error by editing line 87 to:
m = re.match(r'([a-zA-Z.-_]+)=', p)
