Added

- **SegmentProperties** New method "label_format_map" allows you to build arbitrary label formats from dataframe columns using

Fixed

- **SegmentProperties** Nulls in label columns are ignored as intended.

Added

- **SegmentProperties** The `label_col` argument in `SegmentProperties.from_dataframe` can now take a list of column names. Labels are concatenated with a seperator set with `label_separator` that defaults to an underscore (`_`).
- **StateBuilder** Recent segment property arguments included in the segment property maps for SegmentationLayerConfigs.

Changed

- **SegmentProperties** All property names (the `id` field) are coerced to strings, as required.

Fixed

- **SegmentProperties**: Fixed a bug in building tags from dataframes.

Added

- **SegmentProperties**: Tag columns will now automatically disambuguate tags if they are duplicated in different columns of the dataframe.
For example, if you had "my_column" with value "type_a" and "their_column" also with value "type_a", the tag would become "my_column:type_a" and "their_column:type_a". This can be turned off by setting the `allow_disambiguation` argument to False.
- **SegmentProperties**: The `SegmentProperties.from_dataframe` method now has a `allow_disambiguation` argument to control whether the disambiguation above is performed.

Changed

- **SegmentProperties**: Tag property generation performance for long dataframes is improved.


Fixed

- **SegmentProperties**: Fixed a bug in handling tag columns with categorical dtype.

Changed

- **StateBuilder**: When providing a URL but not a client, you will now get a warning that target-site cannot be inferred.

Fixed

- Small changes to work in python 3.8, because the only issue was type hints.

Fixed

- Removed debug statements left in after testing.
