[community] Load Models from Sources like Civitai into Existing Pipelines

[suzukimain]

What does this PR do?

This PR adds an example that allows you to search for models from Civitai and Hugging Face by simply entering a keyword and loading models that meet the criteria into existing pipelines.

Example

!wget https://raw.githubusercontent.com/suzukimain/auto_diffusers/refs/heads/master/src/auto_diffusers/pipeline_easy.py

from pipeline_easy import (
    EasyPipelineForText2Image,
    EasyPipelineForImage2Image,
    EasyPipelineForInpainting,
)

# Search for Civitai
pipeline = EasyPipelineForText2Image.from_civitai(
    "search_word",
    base_model="SD 1.5",
).to("cuda")


# Search for Hugging Face
pipeline = EasyPipelineForText2Image.from_huggingface(
    "search_word",
    checkpoint_format="diffusers",
).to("cuda")

can it use AIR IDs to import them? thanks for this example!

edit: the fact that model API responses has the model type in it we could even do AutoPipeline.from_civitai(air=model_air) kind of thing.
