**Bug fix**
1. Fixed an error in dataset sampling during automatic splitting.
2. Fixed a memory leak when loading images in formats other than `.tif`.
**Changes:**
1. `shuffle` can now be used with both `pre-split` and `split` methods.
2. `offsets` can be specified as floating-point values for dynamic computation.
3. `size` and `offsets` now support mixed formats (i.e., both `int` and `float`).
4. F1 and mAP metrics are now computed by default in `micro`, `macro`, and `per_class` variations.
5. Classes `BoundaryExclusion` and `IntensityDiversification` have been renamed to follow the MONAI naming style.
6. Minor updates to the README for clarity and consistency.
