Add Mode 22 Support

[malibu1320]

Would be nice to work on adding mode 22 support for enhanced PID's. I can assist.

Please, go ahead. github.com/pires/obd-java-api is where it should be implemented.

Do you have any guidance on what needs to be modified? I'm not seeing where the base request header is setup that needs changed. I have the source running locally and connected to my bench PCMs.

Share here what you have and I'll take a look.

Here's an example for GM vs standard OBD. You request on mode $22 with PID "119D". Now I need to see where to adjust analyzing the buffer for a valid response.

public BarometricPressureCommand() {super("01 33");} //Standard OBD PID
public GMBarometricPressureCommand() {super("22 11 9D"); //GM Mode $22 PID

@pires , do you have any tips on how I can implement this? I tried adding new command classes as seen above and adjusting the buffer offset for finding the data but didn't have any luck (yet).

Just override fillBuffer or readRawData, depending on your needs.
