A Swift bindings for llama.cpp

[siuying]

Hi! I have a pet project needs llama.cpp, so I build a Swift bindings.

import Llama

// 1. Open a model
let modelPath = Bundle.module.path(forResource: "gpt4all-lora-quantized", ofType: "bin")!
let llama = try Llama(path: modelPath)
        
// 2. Predict words based on input
let result = try llama.predict("Neil Armstrong: That's one small step for a man,")
print(result)

// 3. Get embeddings given input words 
let embeddings = try llama.embeddings("London bridge is falling down")
print(embeddings)

Hey siuying, that looks like exactly what I need. Does it support Alpaca? If not, I'd love to contribute.
