Release v1.1.0

• Added: audformat.Database.get() method
  to retrieve labels based on their schemes
  and independent of the tables
  in which they are stored
• Added: aggregate_function
  and aggregate_strategy
  arguments to audformat.utils.concat()
  to support overlapping values
  in the objects
  that should be concatenated
• Changed: audformat.Column.get(map=...)
  now returns dtype of labels
• Changed: audformat.Column.get(map=...)
  does no longer raise an error
  if some of the mapped values
  are not available
  when stored in a dictionary
  as scheme labels
• Fixed: avoid deprecation warning
  by replacing
  pkg_resources
  internally with
  importlib.metadata
