[Feature Request] Float64 input

[qhenkart]

What motivated you to submit this feature request?
The openai SDK provides an embedding response of []float64. To interface with the pinecone SDK, I have to loop through every single embed to convert it to float32 and possibly drop precision in the process

Describe the solution you'd like
The pinecone SDK should receive a float32 or a float64

Describe alternatives you've considered
not using the Pinecone SDK for this request and making it manually

Additional context
https://platform.openai.com/docs/api-reference/embeddings/create mentions that the embedding response can be in float32 or float64
https://github.com/openai/openai-go/blob/main/embedding.go#L119 embedding response receives the values as a float64
