SIM card with removed PIN

[Jancs-E]

Hi!
I have an issue using your library with the PIN-disable/removed SIM card - the command AT+CPIN? gives response: +CPIN:READY /OK, but if I simply try to connect either by modem.connect(), modem.connect(pin=None), modem.connect(pin=''), I always get an error ('CME 11 (SIM card PIN is required)'.

How could it be solved?

I found a problem:
originally, the line #431 in modem.py looks so
if cpinResponse != '+CPIN: READY':
which means, it will fail if the response does no contain space.
I modified it so:
if cpinResponse.replace(' ', '') != '+CPIN:READY':
and now it works as it will accept any response - with or without spaces. It also solved my problem.

Would be nice, if you could release an update.
