[FEATURE] Support Vector of numbers binding to numpy.NDArray

[badmonster0]

Currently we're using list for vectors in Python. It's not efficient and needs extra conversions, e.g. when building vector search queries with pgvector like the ::vector here:

cocoindex/examples/text_embedding/main.py

Line 55 in a37eddc

SELECT filename, text, embedding <=> %s::vector AS distance

We want to support vector of numbers represented by numpy.typing.NDArray, e.g. numpy.typing.NDArray[npmpy.float32], numpy.typing.NDArray[npmpy.float64], numpy.typing.NDArray[npmpy.int64] for corresponding types.

#437 is a similar issue - which also added a new Python representation for an existing type.
