Add new variables for temperatures

[xjjiang]

Desired capability or behavior.

GASP has the following variables:

• TDELTO: Increnetal temperature above standard for takeoff.
• TDELLD: temperature increment above standard during landing, deg. F.
• TDELTX: takeoff temperature above standard during mission, deg. F.

It is recommended that Aviary implement this feature.

The main task here I think is to try and add behavior in fortran_to_aviary to catch these variables and translate to an Aviary one. Right now we don't have a way to modify hot day stuff in the atmosphere component directly so we will need to wait for that to be done.

If we decide that we don't want to change atmosphere temperature delta via a variable in the csv (which I think is likely, it probably would be a phase_info option), then we should move those variables to the gasp_deprecated_vars list and close this issue
