`SlidingPatchWSIDataset` builds `ProbMapKeys.LOCATION` with `np.round(...)` and never casts back to int, so `ProbMapProducer` indexes the probability map with floats and numpy 2.x raises `IndexError: only integers ... are valid indices`. Cast at the source so the metadata matches `MaskedPatchWSIDataset`, which already calls `.astype(int)`, and keep a defensive coercion in the handler for datasets that still supply floats. The existing tests only supply integer locations; add a float-location variant of each, which reproduces the error without the handler change. Signed-off-by: Patel, Nilaykumar K <nilapate@amd.com>

Clamp rounded locations to the probability-map bounds.
The iterator can emit the edge patch at (2, 2) for a 4×4 image with 2×2 patches. With mask_ratio == 2, the current calculation rounds its center to (2, 2). A 2×2 probability map has valid indices only from 0 through 1. ProbMapProducer uses this value directly and can raise IndexError.
Clamp the locations to the reported mask size and add an edge-patch test with mask_level > 0.

Reject fractional locations before indexing.
If a dataset supplies location (1.9, 2.0), int() changes it to (1, 2). The handler then saves the probability in the wrong cell without an error. Python specifies truncation toward zero for floating-point values. Validate that float coordinates are finite whole numbers before converting them, and test a fractional location. (docs.python.org)
