Fix flake8 "invalid escape sequence 'x'" warning

From, https://lintlyci.github.io/Flake8Rules/rules/W605.html

As of Python 3.6, a backslash-character pair that is not a valid
escape sequence now generates a DeprecationWarning. Although this
will eventually become a SyntaxError, that will not be for several
Python releases.

Note 'float_pobj' was simply removed from arcstat.py since it
was entirely unused.
