v0.4.3

Added

• Ability to unwrap using isce3's PHASS
• CorrectionOptions model for specifying the correction options in the Workflow config
  • Currently a placeholder for the files which will be used for tropospheric/ionospheric corrections
• Ability to keep relative files in the Workflow config
  • This is useful for keeping the relative paths to the SLCs in the config, and then running the workflow from a different directory

Changed

• Instead of specifying the unwrapping algorithm in dolphin unwrap as --use-icu, the option is not --unwrap-method
  • This let's us add --unwrap-method "phass", but also future unwrap methods without a --use-<name> for every one
• Use spawn instead of fork for parallel burst multiprocessing
  • This leads to the error Terminating: fork() called from a process already using GNU OpenMP, this is unsafe.
    in certain situations, and does not happen with spawn. See https://pythonspeed.com/articles/python-multiprocessing/ for more details.
