Output a finite pulse train on the specified pin using a PIO state machine.

from cubloc import StepPulse
 
StepPulse(pin: int, freq: int, qty: int)

• pin: Output GPIO pin number.
• freq: Output frequency in pulses per second.
• qty: Number of pulses to output.

• TypeError: channel, pin, freq, or qty has an invalid type.
• ValueError: channel, freq, or qty is outside the supported range.

• Note: Pulse generation is handled by PIO, not PWM.
