Fantower throws error trying to set negative fan speeds after bridges on 0% fan layers

[massis87]

Trying to print a preset 0-100 fan tower. It seems after every bridge on the first layer, it's trying to reset the fan speed to -20%.
Manually replacing the S-51 Gcodes for the first layer to S0 fixes it for the first layer.

Klipper logs:
Error on 'M106 S-51 ;AutoTowersGenerator: Resuming fan speed of -20.0% after printing a bridge': S must have minimum of 0.0
