PR Summary

• New module 'data.py' added to the 'fastkml' package
  To increase customizability in handling KML (Keyhole Markup Language) files, a new module has been introduced. This module contains classes that will facilitate the addition of custom data to KML files.

• Introduction of efficient data extraction mechanisms
  To help effectively extract data from XML elements, several classes within the data.py module, namely Schema, Data, SchemaData and ExtendedData, have been updated with a method named _get_kwargs. This provides a more streamlined approach to fetch keyword arguments needed for creating instances of these classes from an XML element.

• Removal of 'from_element' method from 'SimpleField'
  The from_element method previously present in the SimpleField class has been removed.

• Optional parameter 'strict' added to KML document related classes
  The handling of XML elements in KMLDocument, KMLFolder, Schema, KMLPlacemark, and ExtendedData classes, present in kml.py, has been ameliorated with the introduction of a new optional parameter strict in the from_element method. This provides control over strictness while extracting data from XML elements.

• Addition of comprehensive unit tests
  To ensure the effectiveness and accuracy of the new methods, extensive unit tests have been added in the test_data.py module. These tests cover the methods implemented under the Schema, Data, SchemaData, ExtendedData, and data.SimpleData classes.
