possible bug in int2P2H

[Merdele]

the val calculated by the end flag did not make sense as it was calculating a pressure value of ~102 at a higher altitude, which was greater than the previous value of 100 at a lower altitude in test_calc.py

Summary by Sourcery

Bug Fixes:

• Correct the calculation of pressure values in the intP2H function by changing the operation from subtraction to addition when the end flag is true.

Reviewer's Guide by Sourcery

This PR fixes a bug in the interpolation calculation within the intP2H function. The change modifies the formula used to calculate pressure values at higher altitudes by changing a subtraction operation to an addition, which resolves an issue where pressure values were incorrectly increasing with altitude.

PR summary

This Pull Request addresses a potential bug in the intP2H function within the processor.py file. The issue was that the calculation of a pressure value at a higher altitude was incorrectly resulting in a value greater than the pressure at a lower altitude. The fix involves changing the calculation from subtracting to adding a term, which corrects the pressure value computation to reflect a more realistic atmospheric pressure gradient.

Suggestion

To ensure the robustness of this fix, it would be beneficial to add or update unit tests in test_calc.py to verify that the pressure values now decrease with increasing altitude, as expected. This will help prevent similar issues in the future and confirm that the fix works as intended across different scenarios.
