iterate_subdirs
- HIRS.iterate_subdirs(d_start, d_end, **extra)
- Iterate through all subdirs in dataset. - Note that this does not check for existance of those directories. - Yields a 2-element tuple where the first contains information on year(/month/day), and the second is the path. - Parameters:
- d_start (datetime.date) – Starting date. 
- d_end (datetime.date) – Ending date 
- **extra – Any extra keyword arguments. This will be passed on to format self.basedir / self.subdir, in case the standard fields like year, month, etc. do not provide enough information. 
 
- Yields:
- pathlib.Path objects for each directory in the dataset containing files between d_start and d_end.
