No possibility to define WhisperModel compute_type when using GenericLoader with blob_parser=FasterWhisperParser

Checked other resources

[X] I added a very descriptive title to this issue.
[X] I searched the LangChain documentation with the integrated search.
[X] I used the GitHub search to find a similar question and didn't find it.
[X] I am sure that this is a bug in LangChain rather than my code.
[X] The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).

Example Code

import torch
from langchain_community.document_loaders import YoutubeAudioLoader
from langchain_community.document_loaders.generic import GenericLoader
from langchain_community.document_loaders.parsers.audio import (
    FasterWhisperParser
)

device = 'cuda' if torch.cuda.is_available() else 'cpu'
# float32
compute_type = "float16" if device == 'cuda' else 'int8'

yt_video_url = 'https://www.youtube.com/watch?v=1bUy-1hGZpI&ab_channel=IBMTechnology'
yt_loader_faster_whisper = GenericLoader(
    blob_loader=YoutubeAudioLoader([ yt_video_url], '.'),
    blob_parser=FasterWhisperParser(device=device)
    # no possibility to define compute_type
    # Error: ValueError: Requested float16 compute type, but the target device or backend do not support efficient float16 computation.
    # blob_parser=FasterWhisperParser(device=device, compute_type=compute_type)
)
yt_data = yt_loader_faster_whisper.load()

Description

I'm trying to use the FasterWhisperParser class from the langchain_community package to parse audio data. I want to be able to use a GPU if one is available, and fall back to a CPU otherwise.

I'm trying to set the compute_type to 'float16' when using a GPU and 'int8' when using a CPU. However, I'm encountering an issue because the FasterWhisperParser class doesn't accept a compute_type argument. When I try to use a CPU, I get a ValueError because 'float16' computation isn't efficiently supported on CPUs.
