MAXIMUM_HEATFLUX is not found by SU2_PY read_history (header maxHF vs MaxHF)

[ManasBagul23]

Describe the bug

Since cc9e452, SU2_CFD writes the MAXIMUM_HEATFLUX history field with the header maxHF (and d[maxHF], tavg[maxHF], dtavg[maxHF] for the derived fields), but SU2_PY/SU2/io/historyMap.py expects MaxHF. read_history matches headers exactly, so MAXIMUM_HEATFLUX cannot be used as an objective or constraint from the Python scripts.

To Reproduce

Run TestCases/navierstokes/flatplate/lam_flatplate.cfg with HISTORY_OUTPUT= (ITER, RMS_RES, HEAT) for a few iterations, then

import SU2
h = SU2.io.read_history("history.csv")
print("TOTAL_HEATFLUX" in h, "MAXIMUM_HEATFLUX" in h)

prints True False.

Expected behavior

MAXIMUM_HEATFLUX is found like TOTAL_HEATFLUX.

A fix is proposed in #2906.
