Use numba jit instead of njit to remove warning

[quentinblampey]

One-character PR to remove the following warning during the import of spatialdata:

RuntimeWarning: nopython is set for njit and is ignored

Very minor PR, not urgent.
See here the difference between numba.jit and numba.njit.

I was annoyed about this warning when running segmentation: for instance, with 50 workers, the warning gets duplicated 50 times and breaks the progress bar.
