### Changed

  - The export handlers for "storeroom" and "vault-native" configuration
    data,
    [`export_storeroom_data`][derivepassphrase.exporter.storeroom.export_storeroom_data]
    and
    [`export_vault_native_data`][derivepassphrase.exporter.vault_native.export_vault_native_data]
    configuration data now both support a unified interface:
    [`ExportVaultConfigDataFunction`][derivepassphrase.exporter.ExportVaultConfigDataFunction].
    A new dispatch function
    [`export_vault_config_data`][derivepassphrase.exporter.export_vault_config_data]
    automatically calls the correct backend, based on the requested format.

    This is a **breaking API change** due to the change in function
    parameter names and return types.
