"useChryslerMAPCorrection" Is Broken

[FlashStopFall]

useChryslerMAPCorrection has been broken since commit 419973f, with the last working version being commit a50af8e. (Arduino nano 328p, legacy board, legacy LCD, legacy buttons, but it doesn't compile for any board).

Commit 419973f (above) gives a different error (Compilation error: 'prgmCalculateMAPpressure') was not declared in this scope than the current main/develop build (Compilation error: 'tPressureChannel' was not declared in this scope). The earliest commit I happened to track this to was e6930e7.

It appears some code was moved out of trip_measurement.h and functions.h into trip_measurement.ino, and that broke things.
