Permission issues when running EnergyPlus simulation with user not having write permissions for bim2sim assets directory

[jgerster-wetec]

In https://github.com/BIM2SIM/bim2sim/blob/development/bim2sim/utilities/common_functions.py files are opened in 'r+' mode.
Is that really necessary, or would it be possible to open them in read only mode to avoid write permission issues?
