Change the gesture behaviors - Conductor

[sandbenders]

In 'https://github.com/DigiScore/RAMI2/blob/main/modules/conducter.py', line 118:

        # Get length of gesture
        phrase_length = (randrange(300, 800) / 100)  # + self.global_speed

The 'phrase_length' is hard coded. Change it to something we can change the min and max values (config file or other solution).

Line 171 (subdivision)
# Generate rhythm rate here
rhythm_loop_end_time = time() + (randrange(500, 2000) / 1000)

Line 176 (speed range)
arm_speed = randrange(30, 200)
if self.XARM_CONNECTED:
self.drawbot.set_speed(arm_speed)
