error in RMC parsing

My device (Ublox ZED-F9P) submits an empty course value when the device is stationary, for example:

['GNRMC', '051003.00', 'A', '100', 'N', '100', 'E', '0.124', '', '080122', '', '', 'A', 'V']

which fact invalidates current parser here:

I do not know what is your favourite solution to that so I am not submitting a pull request, but it should be fixed in some way 😃

Hallo, heading and course are different! A gps-unit can only calculate a course, when it is moving. No move no course. And it can not calculate a heading. It is correct, not to send a course, when not moving. Or if the speed os zero, then the course is not usable. Greetings romeotango

I’ve noticed it before but I do not see a problem with heading 0 if stationary. It really does not matter whilst parsing the file later.

We do not have any other data than content of GNRMC message. What I am working on currently is to have no value which would work with other parts of the code.
