increased SYNC_DETector frequency up to 2.42 MHz. also now ADC clock freq is equal to Mach-Zander freq. Because ADC samples at both rising and falling edges

implemented setting HIGH of OUT_6, OUT_7 at 1/3 and 2/3 of laser current change cycle. Both are reseted at the end of cycle. their purpose -- switch amplifier stages of signal after detector, before ADC. NOT TESTED!

Now PG9 toggles at the very beginning of every laser current step. Purpose: tell ADC that step started/ended for correct averaging.

modified ADC trigger: now it starts before ADC samplig (as it was), stops after some ADC clocks (while in current varying routine)

fixed relative phases in Mach-Zander and ADC clocks. ADC clock delayed to move ADC sampling time far from the start of modulated period. Now there is 400 ns time reserve.

partially solved issue with random modulator and ADC clock stopping at the end of ЛЧМ. Done: when we want to stop clocks -- enable IRQ on sloewr clock (TIM11). In IRQ switches TIM4, TIM11 to one-pulse mode, disables IRQ. When we starting these timers th next time -- we resets their counters, one-pulse mode disables.
