Add `coordinate_space` to `Scene.create` (#249)

Allow user to specify the scene coordinate space on creation.

Update the MultiscaleImage API (#238)

* Directly take the `CoordinateSpace` as a creation parameter.
* Remove confusing `image_type` property/creation parameter. Use `data_axis_order` instead which uses the axis names the user provided.
* Create the first resolution level when creating the `MultiscaleImage`.
* Require the `add_new_level` to only add images smaller than the base (level=0) image.
* Add a `set` method for adding images that exist outside of SOMA.
* Add a property to check the number of channels in the image.
* Remove `ImageProperties` class.

rm py3.9 `__subclasscheck__` workaround (#240)

It seems to be causing issues in TileDB-SOMA CI
(single-cell-data/TileDB-SOMA#3246),
and it doesn't seem to be necessary for any tests.

Replace `axis_name` with `coordinate_space` in spatial dataframes (#237)

Directly use the `CoordinateSpace` class instead of  a tuple of "axis names" in the creation methods for the `PointCloudDataFrame` and `GeometryDataFrame` classes.

Fix typos in Scene `add_*` methods (#234)

Rename PointCloud -> PointCloudDataFrame (#232)

Add spatial presence matrices (#221)

This adds dataframes for creating a join table between the scenes and observations/variables. New methods are added to the `ExperimentAxisQuery` class for getting a Arrow array of scene names that relate to the obs or var in the query.
