* fix dtype depending on numpy version
numpy v2 np.array returns int64 which Tensor passed through for the
first decode call, swallowing the <|notimestamps|> token and corrupting
the sequence
* fix whisper OOB
global limit on whisper's context length
* enforce whisper max_tokens_to_sample (match openai)
local limit on max tokens decoded
* add quantize fp8 in llama3
* don't truncate fp8 alu result
* cast to float32 before matmul
* --model weights/LLaMA-3/8B-SF-DPO/
