Polyclonal

----
- Fix bug in ``plot.lineplot_and_heatmap`` where the ``minimum max of <stat> at site`` failed to keep only the top sites when the hide-not-filter option was being used. Addresses `this issue <https://github.com/dms-vep/dms-vep-pipeline-3/issues/107>`_.

----
- Fixed ``altair`` plots to work with ``numpy`` version 2, which caused problems in some cases apparently due to a data type conversion issue.
- Add ability to specify specific regions for each model in ``PolyclonalCollection``. This adds the ``region_col`` parameter and the ``PolyclonalCollection.regions`` and ``PolyclonalCollection.n_models_by_site`` attributes. Related to adding functionality to address `this issue <https://github.com/dms-vep/dms-vep-pipeline-3/issues/160>`_.

----
- Switch to using ``scipy.sparse`` arrays rather than matrices to keep up with `this <https://github.com/jbloomlab/binarymap/issues/6>`_ `change <https://github.com/jbloomlab/binarymap/pull/7>`_ to ``binarymap`` (now require ``binarymap`` >= 0.7).
- Remove pin on ``urllib3``

----
- In ``lineplot_and_heatmap``, add ``mean_abs`` and ``sum_abs`` as possible site statistics, reflecting the mean and sum of the absolute values of the mutation values.

----
- In ``lineplot_and_heatmap``, mutations that are hidden are by one slider filtered even if they fail other sliders. Addresses `this issue <https://github.com/dms-vep/dms-vep-pipeline-3/issues/96>`_

---
- Added ``rename_std`` option to ``lineplot_and_heatmaps``, which fixes a quasi-bug introduced in the ``rename_stat_col`` option by the changes in version 6.8.
