Power-cycles the target.

Implementation-wise this actually causes a full glitch to be run, but with
trigger, delay, pulse, and glitch-output disabled. This means that a power-cycle
will also fill the ADC.

power_cycle_length and power_cycle_output are taken from the glitcher configuration by default, if not overriden.

:param power_cycle: Output to toggle the powercycle. If not provided, this will be the value supplied during configure_glitcher().

Please change to power_cycle_output :)


- `OUT_CROWBAR`: Route the power-cycle to the gate of the Crowbar MOSFET.
- `OUT_MUX0`: Route the power-cycle to control channel 0/X of the analogue switch (the one exposed on the SMA connector).
- `OUT_MUX1`: Route the power-cycle to channel 1/Y of the analogue switch (exposed on 20-pin header).
- `OUT_MUX2`: Route the power-cycle to channel 2/Z of the analogue switch (exposed on 20-pin header).
- `OUT_EXT0`: Route the power-cycle signal to the EXT0 header. Useful to trigger external tools such as a ChipSHOUTER or laser.
- `OUT_EXT1`: Route the power-cycle signal to the EXT1 header. Same as above.
- `OUT_NONE`: Disable power-cycle generation.

:param power_cycle_length: The number of clock-cycles for the power cycle. If not provided, this will be the value supplied during configure_glitcher().
