Bug summary

Loading a marvin.Image from a local file raises a value error -- please see below. The error comes because the split method is being called on a PosixPath object, which does not have this method. The fix is to change line 297 of marvin/types.py to format = path.suffix.lstrip('.').

I'm happy to give a pull request with this small change if its helpful.

<the rest of the image class...>
    @classmethod
    def from_path(cls, path: Union[str, Path]) -> "Image":
        with open(path, "rb") as f:
            data = f.read()
        #format = path.split(".")[-1]
        format = path.suffix.lstrip('.')
        if format not in ["jpg", "jpeg", "png", "webp"]:
            raise ValueError(f"Invalid image format: {format}")
        return cls(data=data, format=format)

Reproduction

import marvin
from pydantic import BaseModel

class MyModel(BaseModel):
    account_number: str

from pathlib import Path
img = marvin.Image(
    Path("example_image.jpg"),
)
result = marvin.cast(img, target=MyModel)

Error
