OpenAI route "/v1/embeddings" ignores encoding_format

[shedar]

Docker image: runpod/worker-infinity-embedding:1.1.4

According to the embeddings api reference, encoding_format param can be "float" (default, returns the embeddings vector as a list of floats), or "base64" (returns the embeddings vector as a base64 encoded array buffer).
The docker image returns embeddings as a list of floats regardless of the parameter value.
It'd be great to support it, or at least throw a proper error to indicate that value is not supported.
