Documentation for the get*JSON and getObject* functions

[subos2008]

Having coded up everything using reader.getRows() I noticed their appear to be a set of undocumented utility functions that - I assume - combine all the column header and row values into an array of objects?

Could we get example cases for reading/writing using objects into the docs? I'm pretty nervous about how fragile the lower level interface is when my schema changes.

Once again - thanks for wrapping DuckDB for us! Super useful tool.

See the section "Convert Result Data to JSON" in the docs on the NPM page. The docs on duckdb.org are a bit out of date; I'll work on getting them updated.
