Description
The correct scale normalization for LoG should be -σ^2 instead of -σ in the multiLoG function called by blob_LoG.
In addition, the docstring of BlobLoG says:
radius is equal to σ√2
but
radius is equal to σ√N for a N-dimensional image
is more accurate.
This error is easy to fix and I can handle it on my own (please note that this will be my first PR so any guidance is much appreciated!).

Research direction
Locate the multiLoG function called by blob_LoG and the BlobLoG docstring. Check the current normalization and radius wording against the issue description, then review nearby tests or examples for expected behavior. Done means both corrections are reflected and the relevant existing checks still pass.
