Version 0.3.0

Added

• pds.datetime.fromisozformat() function.
• pds.pid.VISID.compression_class() function.
• pds.xml.py added, very minimal, functionality may be moved.
• vis.db.raw_products.RawProduct.from_xml() function.
• vis.db.raw_products.RawProduct.asdict() function.
• vis.pds.create_raw.check_bit_depth() function.
• vis.db.create_vis_dbs convenience program to add empty tables to database.

Changed

• Updated templates and modules for PDS information model 18.
• vis.db.raw_products.RawProduct has some improved error-checking in init() and
  validate_datetime_asutc().
• vis.db.raw_products.RawProduct product_id column is now unique in database.
• vis.db.raw_products.RawProduct md5_checksum changed to file_md4_checksum to
  clearly associate it with the other properties that begin with "file_".
• vis.pds.create_raw.tiff_info() no longer raises an error if a bit depth other than 16
  is provided.
• vis.pds.create_raw now creates .JSON output files by default instead of XML PDS4
  labels, but XML files can still be made.
• carto.heatmap.write_geotiff_rasterio now supports compressed output and defaults to "deflate"

Fixed

• carto.tri2gpkg.replace_with() now correctly returns a float value in all circumstances.
• pds.pid.VIPERID.datetime() now properly returns datetimes with a UTC timezone.
• vis.db.raw_products.RawProduct.label_dict() now correctly sets sample_bits and
  sample_bit_mask if the image is a SLoG image.
• Added init.py files to all modules (some modules did not get incorporated into the
  PyPI package because they did not have init.py files.
• The setup.cfg now properly includes requirements that vipersci needs.

Removed

• Many modules still had if __name__ == "__main__" constructs from early development
  which are now not needed with the entry points in setup.cfg.
