[draft] excess image resize maintain aspect ratio

[mcembalest]

Currently images seem to get hard-adjusted to 512,512 if either width or height exceeds 512

we have a helper function to resize images while maintaining aspect ratio so this PR re-uses it

---

Important

Replace hard-coded image resize with resize_pil() to maintain aspect ratio in dataset.py and embed.py.

• Behavior:
  • Replace hard-coded image resize with resize_pil() in _add_blobs() in dataset.py and image() in embed.py to maintain aspect ratio.
• Functions:
  • Move resize_pil() from embed.py to utils.py for reuse.
• Imports:
  • Add resize_pil import to dataset.py and embed.py.

The new helper function resize_pil computes the downsize_factor using integer division (e.g. width // max_width), so for images only slightly above 512 (e.g. 600×700) the factor is 1 and no resizing occurs. Consider computing a floating‑point scale factor (e.g. scale = min(max_width/width, max_height/height)) and then resizing with new dimensions (int(width*scale), int(height*scale)). Also, specify a resampling filter like Image.LANCZOS for better quality.
