v0.1.8

Fixed a long-standing performance issue with loading the python module. Imports are now done on demand, shaving ~4 seconds off loading the library (including starting the server or running any of the scripts).

Improved ingest flow #34 implemented. When data is ingested we now:

• Check types of columns and generate summary statistics. this will enable future UI
• Check for array columns and suggest importing those as embeddings
• Check for name collisions when uploading a dataset, giving a warning if a collision is detected
