BLTouch deploy probe and retract probe macros might be better without I1 #75

The macros to deploy and retract the BLTouch probe didn't function for me until I removed the I1 parameter.

https://github.com/railcore/configs/tree/master/duet/sys/config-user%20examples

After some Discord discussion, it appears the I1 is needed if you are connecting the servo to the Duet board on the connector that most of us use to connect to the Duex5. If you connect the server to a PWM port on the Duex5, it appears you don't want the inversion.

I also note that @kraegar did not have the inversion in his deploy and retract macros.

No idea where these have come from. I'm not a BL-touch user.

What would be best here? Changing the default and putting a note for people connecting via PWM?

Well -for RailCore, I'd suggest we remove the I1 since the default Duet RailCore user will have the Duex5. We could leave a note and say that if the user connected to the Duet instead of the Duex, then they would need to add I1.
