Version 1.0

Simplified the repo organization, setup process, and schema browsing for users.

Future development might improve the spotty header deduction from .sql files queries and add * wildcard support. A proper header solution likely requires legitimate parsing, instead of a regex hack. However the regex is currently working most of the time. I imagine the wildcard support requires a polars query at runtime to get column names from a schema .parquet file on the fly (or generate that file and then query it).
