Vectors only support `f32` - should also support `f64`

[jpmcb]

I noticed that the vectors only support f32 floats:

https://github.com/qdrant/rust-client/blob/cd7ee0f5946bdf4d5c49de438230f8f9d337a6fc/src/qdrant.rs#L2037-L2042

and I ran into an issue attempting to load PointStructs that are of Vec<f64> (using embeddings generated from an ollama rust client.

/// An embeddings generation response from Ollama.
#[derive(Debug, Deserialize, Clone)]
pub struct GenerateEmbeddingsResponse {
    #[serde(rename = "embedding")]
    #[allow(dead_code)]
    pub embeddings: Vec<f64>,
}

Trying to use this vec f64 results in:

Steps to reproduce

1. Bootstrap qdrant client, collection, etc.

let qdrant_client = QdrantClient::from_url("http://localhost:6334").build()?;
let collection_name = "test";

qdrant_client
    .create_collection(&CreateCollection {
        collection_name: collection_name.into(),
        vectors_config: Some(VectorsConfig {
            config: Some(Config::Params(VectorParams {
                size:  384, // size of the all-minilm embeddings
                distance: Distance::Cosine.into(),
                ..Default::default()
            })),
        }),
        ..Default::default()
    })
    .await?;

2. Bootstrap olllama client:

let ollama = Ollama::default();
let ollama = Ollama::new("http://localhost".to_string(), 11434);

3. Generate an embedding using the ollama client - this is a Vec<f64>

let embedding_model = "all-minilm".to_string();
let embedding_prompt = "Woof woof, bark bark".to_string();
let embedding_resp = ollama
    .generate_embeddings(embedding_model, embedding_prompt, None)
    .await
    .unwrap();

4. Attempt to use it in a PointStruct and notice error.

let payload: Payload = json!(
    {
        "test": "this is a test",
    }
)
    .try_into()
    .unwrap();

let point = vec![PointStruct::new(0, embedding_resp.embeddings, payload)];
client
    .upsert_points_blocking(collection_name, None, point, None)
    .await?;
