 There is currently a function for adding metadata to a registered script
 (`wp_script_add_data()`), but no function for retrieving that metadata.

 '''My use case'''
 I am trying to write a unit test for a function in my plugin that
 generates data and calls `wp_localize_script()` to ensure the expected
 data is passed for localization.

 '''Other Use Cases'''
 I could see other use cases where a plugin could change a metadata value
 or add a new key if a certain value is assigned to a certain key.
