Fuell pressure corelated injectors deadtime #771

Many injectors have aviable deadtime correction data , in reference to fuel presssure.
As this change is nonlinear. it would be beneficial to have 2nd vector similar to voltage dependency. This two vectors would create good enought estimation, of what deadtime tuned injector have. Final logic is just multiply actual voltage cerelated deadtime with fuell pressure one. and you have final deadtime.

i already tried did some cofding but im not sure if that should be done this way , patch is as small it could get. Only part im missing is getting the default values to be 1 insetad of 28k
