ultravox 0.4.1 doesn't work with vllm

[Madoshakalaka]

with the dependency:

[tool.poetry.dependencies]
vllm = {extras = ["audio"], version = "^0.6.6.post1"}
transformers = "^4.47.0" # same as ultravox main branch

following this example here:
(but with "fixie-ai/ultravox-v0_3" changed to "fixie-ai/ultravox-v0_4_1-llama-3_1-8b")

https://github.com/vllm-project/vllm/blob/0794e7446efca1fd7b8ea1cde96777897660cdea/examples/offline_inference/audio_language.py#L27-L45

the error I got:

[rank0]: Traceback (most recent call last):
[rank0]:   File "/home/ME/Projects/my-project/./main.py", line 28, in <module>

@petersalas I am not sure if the vllm example needs to be updated to work with the latest ultravox model. Please take a look.

I think the issue is that for some reason the UltravoxProcessor isn't registered as an AutoProcessor in our recent HF models. (vLLM recently changed to depend on UltravoxProcessor)

Will take a look this week.
