When invoking runqemu with Python 3.12, the following warning is encountered:
|SyntaxWarning: invalid escape sequence '\.' This is because the interpreter scans the string before it is processed by the regex module, and it interprets the backslash as part of an escape sequence, but not a standard one. This will be registered as an error rather than a warning in future Python versions. To avoid the it, simply add an extra backslash so that Python doesn't misinterpret the string, while the regex parser still sees an escaped '.' character.
