Steno3d

Bug fixes

- Pinning to `properties==0.4.0` caused dependency issues across other libraries. Steno3D is compatible with all versions of properties (up to 0.5.6, at least), so pinning is unnecessary.

Bug Fixes
- During project download, array types are now treated correctly, ensuring we don't try to read int data as floats and vice versa (See: https://github.com/seequent/steno3dpy/pull/158 and https://github.com/seequent/steno3dpy/pull/159)
- During project upload, unset `Z` value on `Mesh2DGrid`s is correctly ignored (See: https://github.com/seequent/steno3dpy/pull/158)

Minor Changes
- `from_omf` conversion now supports continuous and category data, as well as better colormap support

Major Features
- You can now save a Steno3D Project to OMF file. This compliments the existing `from_omf` behavior.

Minor Changes
- Converting Line resource to OMF now respects `view_type`/`subtype`

Minor Changes

- Github links, etc, updated for Seequent organization

Bug Fixes
----------
- steno3dpy is now compatible with the latest `properties` release, v0.4.0
