Run SIA python scripts upon rebuild of Hive / creation of installer

[maxenceryan]

• Builds the compile python scripts upon rebuilds
• Assumes python is on PATH (as in, you are in a conda environment when running this)
• the python scripts are for python 3! so i have two conda envs: hive with python 2 and hive3 with python 3. THis can easily be changed back to python 2 if needed. Only difference is where to put the encoding kwarg when writing the jsons
• changes in python scripts are not relevant to issue, just separating out the concern of compiling SIA 2024 data vs compiligin/generating the schedules (since interpretation was needed). Should be part of adaptive comfort PR Sia380 - Adaptive comfort setbacks #595

Closes #605
