* [example] batched-bench "segmentation fault"
When `llama-batched-bench` is invoked _without_ setting `-npl`, "number
of parallel prompts", it segfaults.
The segfault is caused by invoking `max_element()` on a zero-length
vector, `n_pl`
This commit addresses that by first checking to see if the number of
parallel prompts is zero, and if so sets the maximum sequence size to 1;
otherwise, sets it to the original, the result of `max_element()`.
Fixes, when running `lldb build/bin/llama-batched-bench -- -m models/Meta-Llama-3-8B.gguf`

* add truncate_bf16
* truncate intermediate fp32 if converting bf16 to bf16
* fix masking in __compute_fp32_to_bf16
* np.int16 no longer used
* missing cast and additional numpy 2.x fix
* ggml-impl : do not flush bf16 subnormals to zero
* ggml : add reference fp32 to bf16 conversion
The fast version is no longer equivalent for all platforms
because of the handling of subnormal values.
* gguf-py : remove flush to zero for bf16 subnormals
* gguf-py : remove float32 truncation to bf16
Rounding achieves the same thing in the cases where this was used.
* missed prototype update in merge
* merge cleanup

I was wondering if there was a specific reason for `if val` but good to hear we can safely use `len(val == 0`

In these codes, we want to retain the value that they previously held
when mask[i] is false. So we should use undisturbed. With the default
agnostic policy of rvv intrinsic, these values can be held or be
written with 1s.

The token immediately before an eot token was lost when SSE streaming
was enabled if that token was contained entirely within a stop sequence.
As an example of when this could happen, consider this prompt:
Type the phrase 'pleas' once.
In a Llama 3-derived model, 'pleas' tokenizes as 'ple' 'as'. The token
'as' is contained within this instruct mode stop sequence:
<|eot_id|><|start_header_id|>assistant<|end_header_id|>
due to the word 'assistant'. Since `string_contains_sequence_substring`
returns True for 'as', this token is added to `tokenReserve` instead of
being streamed immediately. If the '<|eot_id|>' token was generated
next, the text in `tokenReserve` would be discarded.
