Gps part 1 - reading position

[rtlopez]

Added support for gps module communication

• gps module baudrate will be detected and changed according to setting in ports tab
• navigation options of gps module will be automatically updated
• gps reading should be visible in GPS tab

To make it work you need to

• connect GPS module to unused serial port
• enable GPS feature
• select GPS Sensor on specified UART in ports tab
• set recommended speed to 115200, note that it must be set in Configuration/MSP column, not Sensor/Input

Keep in mind that

• it is barely possible to get fix at home, you have to place receiver close to opened window, or outside ideally.
• If your module was not used for a long time, you might need to wait several minutes to get fix.
• recommended module is Ublox M8 or never, M7 or M6 aren't realiable, accurate enough and might not work at all, I don't even have any to test, so if you have and can test, please share your results.

To see a result of initial communication go to the CLI ind type logs.

In the CLI there is also new command that shows gps status and raw data, for this purpose type gps.
