Summary: This PR sets a minimum version constraint (>=4.57.1) for the transformers dependency.

Context: The recent PR #184 (eb7382f) added support for 'fast' ImageProcessor using use_fast=True in AutoImageProcessor.from_pretrained(). This requires a minimum version of transformers that supports the fast image processing feature.

Changes reviewed:

- "transformers",
+ "transformers>=4.57.1",

Assessment:
The change looks good. Adding a minimum version constraint is the right approach to ensure compatibility with the newly added fast image processor feature. The constraint is appropriately placed in pyproject.toml alongside other versioned dependencies.

Minor suggestion: Consider adding a brief PR description explaining why this specific version is required (e.g., "Required for use_fast=True support in AutoImageProcessor introduced in PR #184"). This helps future maintainers understand the rationale.

Verdict: Approve - straightforward dependency version bump to support a recently added feature.
