Sebastianv650andScott Lahteine 9818d97587 Fix Z-hops during retract/prime lead to blobs 
We don't want to have retract/prime movements done with LIN_ADVANCE, that's also true with simultaneously executed Z-hops.

Sebastianv650andScott Lahteine 599649e45d Add formula for LIN_ADVANCE_K 
With this formula, a start value for K for further fine-calibration can be calculated.

Sebastianv650andScott Lahteine a448cedbc5 LIN_ADVANCE bug fix and optimization 
.) long to int: Extruder stalls at 10kHz / 20kHz step limits with long.
.) Take the delta_adv_steps calculation out of the step_loops loop. Wasted calculation performance if done inside.
.) >> 2 replaced by 3: Is divide by 8. Reason: Timer 0 runs at 16/8=2MHz, Timer 1 at 16/64=0.25MHz. ==> 2/0.25=8.

Sebastianv650andScott Lahteine 0c5192b288 Patch LIN_ADVANCE timing issue 
Also the extruder stepper ISR has to keep an eye on step_loops count.
