Typros in Version 0.7b4

[mc0110]

Hi,

first of all I would like to thank you for this fantastic library. I use it to transfer the control commands for a LIN-BUS control unit. This works very well. The library not only works on an ESP32 but I also tested it on an RP2 pico W.

I loaded the version via PyPI and get 0.7b4 as the latest version. I find log.warnings in lines 678 and 690 which abort with an error. I use the MicroPython version 1.19.1-608.

Thanks
Magnus
