docstr: This function is meant to compress the input paths, and it specifically doesn't use
  `metaflow.util.compress_list` under the hood. The reason is that the `AIRFLOW_MACROS.RUN_ID` is a complicated
  macro string that doesn't behave nicely with `metaflow.util.decompress_list`, since the `decompress_util`
  function expects a string which doesn't contain any delimiter characters and the run-id string does. Hence, we
  have a custom compression string created via `_compress_input_path` function instead of `compress_list`.
