Unescaped + character in hlapi.py results in utf-7 codec error

[OneDevTwoDev]

The '+' character is not escaped in the following comment in hlapi.py

python-TSIP/tsip/hlapi.py

Lines 109 to 111 in 79414f2

	# Possible structs for packet ID + subcode
	#

This results in the following error being generated when attempting to import tsip on Python 3.9 or greater:

SyntaxError: 'utf7' codec can't decode bytes in position 2906-2907: ill-formed sequence

[darkk]

It's coding: utf-8 since 7f293b8.

I suggest to close this issue and PR #37 as fixed in master.
