fixed dependency on Firmware repo in makefile
updated upload script, fixes bad character error message
-added micro second counter to increase precision
-enabled low light mode without HDR but increased desired brightness
-extended I2C frame with accumulated flow/gyro values between readouts
readout check of new I2C frame prohibits compatibility with old version, implemented 2 checks, compatible with old I2C readout know
I2C frame1 and frame2 are now totally independent, both protected during readout
added serial output throttle factor, adjusted i2c integral frame to output millirad*10, cleaned up main loop and I2C tx update function
Update MAVLink, use default dialect
Change to default / common dialect
Fix API and repeated declarations of UART interfaces, fix meaningless parameter index comparison
Updated MAVLink version
Removed unused dialect
added optical_flow_rad mavlink message, added gyro_temperature to I2C and mavlink interface
