Adding GNU GPL v3.0 license to the branch

Finished updates to support the new MAU 1.1 firmware: 1) Adjusted Flight Profiles to match transition between sampling rates. 2) Created folder MainDev for the GraphGenerator and updated the program to support timestamps generation. 3) Updated the Excel sheet to support timestamps and adaptive chart lenght. 4) Moved old GraphGenerator and Excel sheet implementations to folder "old". 5) Added .bat files for reading and erasing the EEPROM to source control.

VERSION READY FOR TEST IN ROCKET. Set first NVM position to receive a sample at address 0x08 right from the call to rawdata_readout_cycle() from main().

Wrapped the call to report_apogee in #ifnotdef TEST_MODE and FLIGHT_SIM

Minor comment fixed.

VERSION FOR TEST IN REAL ROCKET.

Changed flow section naming comments

Merged calls to rawdata_readout_cycle to one call only. Process type is switched from DETECT_ASCENT to DETECT_LANDING inside of DETECT_ASCENT high variance detected condition. Removed other useless stuff, like MEASURE_GROUND_PRESSURE LED control case.

Removed useless cycles number limiter related variables and some trash.

Worked with several simulated flight samples set. It is possible to select FLIGHT_SIM mode and several flight profile headers that replace the readings from the actual barometer.
