Graphistry

Added
* `g.transform()`
* `g.transform_umap()`
* `g.scale()`
* Memoization on UMAP and Featurize calls
* Adds **kwargs and propagates them through to different function calls (featurize, umap, scale, etc)

Breaking 🔥

* Final deprecation of `register(api=2)` protobuf/vgraph mode - also works around need for protobuf test upgrades

Added

* `register(..., org_name='my_org')`: Optionally upload into an organization
* `g.privacy(mode='organization')`: Optionally limit sharing to within your organization

Changed

* docs: `org_name` in `README.md` and sharing tutorial

Added

* `compute_igraph()`
* `layout_igraph()`
* `scene_settings()`

Fixed

* `from_igraph` uses `g._node` instead of `'name'` in more cases

Fixed

* `g.from_igraph(ig)` will use IDs (ex: strings) for src/dst values instead of igraph indexes

Major version bump due to breaking igraph change

Added

* igraph handlers: `graphistry.from_igraph`, `g.from_igraph`, `g.to_igraph`
* docs: README.md examples of using new igraph methods

Changed

* Deprecation warnings in old igraph methods: `g.graph(ig)`, `igraph2pandas`, `pandas2igraph`
* Internal igraph handlers upgraded to use new igraph methods

Breaking 🔥

* `network2igraph` and `igraph2pandas` renamed output node ID column to `_n_implicit` (`constants.NODE`)

Fixed

* Expose symbols for `.chain()` predicates as top-level: previous `ast` export was incorrect
