Add flag in config for sweep mode

Browse Source 
#define FREQ_MODE_START_STOP    0x0
#define FREQ_MODE_CENTER_SPAN   0x1
Now sweep mode not defined from frequency0 > frequency1 or frequency0 < frequency1
frequency0 always < frequency1

All freq must get by use get_sweep_frequency(mode)

Revert Select CH0 reflect channel before set freq, add additional delay on 0 sweep point
