Fysetc Cheetah v1.2 boards require a special sequence to reset reliably.
This sequence works for me in all cases. Simpler sequences without
double reset did not work correctly. This is likely because of a weird
stateful circuitry for toggling the bootloader state.
Cheetah boards use RTS to configure bootloader triggering. By default,
pySerial sets RTS on connect, which unfortunately configures the board
to start the bootloader on reset.
Add a toggle for the RTS state to allow users to workaround. The RTS state
is set before the serial connection is opened, so there are no glitches.
Addresses #2026.

Once a hop is performed, it will only be re-issued if the z-axis has been

When z-axis is homed, x and y positions are known. When setting this
boolean option, these are set back to their last positions.
Whenever a hop is specified it is re-issued after the Z axis has been
homed. This is especially necessary when a pressure-based probe is used.
Also, the module decides if a hop is necessary, based on either a known
Z position or a flag that is set whenever the motors are disabled.
