Added status_string method to return simple status strings

[tamenol]

status_string returns the current status of the bus in a single word.

Ok, so I have no idea this is warrented to get merged. I wrote this function as I needed a single word for the status of the bus (just like you have in PCAN-View). And I didn't want to import .basic in my project to get the needed values, hence why I put it in the PcanBus class

I' return None in this case, to make it more explicit that something went wrong.

[tamenol]

Yes, good idea. However, when looking back on this, wouldn't it be better if I made a dictonary with all the errors and their strings in basic.py and retrieve them with this function, so the class in pcan.py doesn't get cluttered much?

@felixdivo see commit 890128f

[felixdivo]

Sorry for the long delay, do you still have tome to fix this?

[tamenol]

@felixdivo No problem. And yes, I'll have a look this weekend/in the course of next week.

[felixdivo]

Looks good to me.

Except the formatter is complaining here. You can fix it by executing black . in python-can/can/.

What a massive change 👍
