Navis

This is a bug fix/maintenance release:

1. Fixes an issue with reading the template meta data on Windows (11)
2. Will no longer automatically create a `~/flybrains-data` directory (10)

Lots of under-the-hood improvements and bug fixes. In particular, these changes should make subclassing of navis' neuron objects easier. See [here](https://navis.readthedocs.io/en/latest/source/whats_new.html) for the full change log.

Hot fix for a bug in 0.2.1 that prevented registering some/all transforms under certain conditions.

This is a maintenance release.

This version has a couple important additions/changes:

1. Added VirtualFlybrain.org's VNC templates, meshes and CMTK transforms (thanks to Robbie1977): see the new `download_vfb_transforms()` function
2. Added a function to download JRC VNC H5 transforms: `download_jrc_vnc_transforms()`
3. For consistency renamed `download_saalfeld_transforms` -> `download_jrc_transforms`
4. Added a landmark-based FANC <-> MANC transform

This version fixes a critical mistake that led to the Jefferis lab's CMTK being registered with the wrong orientation.
