For Pandas, it appears we could eventually implement an ExtensionArray so that Pandas can operate directly on Vortex arrays.

@robert3005 Is LayoutWriter a requirement? I'm using StreamArrayWriter to write and I'm able to read that again using StreamArrayReader. All my round-trip tests have passed thus far.

[robert3005]

The StreamArrayReader/Writer are purely for serialising arrays without much framing. LayoutWriter is our logic for writing the file format which involves encoding arrays with prunable layouts
