verbose doesn't work + writing non-error messages to stderr

It's very frustrating that a lot of messages get written to stderr, like model parameters that are very difficult to differentiate from errors. I tried to capture stderr but then also error messages get lost.

My suggestion is to go with Python standards, i.e. print errors only to stderr; all other should go to stdout.

verbose=False doesn't work either

Steps to Reproduce
llm = LlamaCPP(
# You can pass in the URL to a GGML model to download it automatically
model_url=model_url,
# optionally, you can set the path to a pre-downloaded model instead of model_url
model_path=None,
temperature=0.1,
max_new_tokens=256,
# llama2 has a context window of 4096 tokens, but we set it lower to allow for some wiggle room
context_window=3900,
# kwargs to pass to call()
generate_kwargs={},
# kwargs to pass to init()
# set to at least 1 to use GPU
model_kwargs={"n_gpu_layers": 1},
# transform inputs into Llama2 format
messages_to_prompt=messages_to_prompt,
completion_to_prompt=completion_to_prompt,
verbose=True,
)

verbose=False doesn't work + stderr get written:
