Additions
- New `plot3d` parameter: with plotly backend, use `fig` to add data to existing plotly figure
- New `plot3d` parameter: with vispy backend, use `center=False` to not re-center camera on adding new data
- New `r.mirror_brain` parameter: use e.g. `via='FCWB'` if source space does not have mirror transform
- New `NeuronList` method: `append()` works like `list.append()`
- First implementation of smarter (re-)calculation of temporary Neuron properties using `.is_stale` property
- Neurons can now be multiplied/divided by array/list of x/y/z coordinates for non-isometric transforms
