Improve safety of multi-threaded interpolation #543
Description
The usage of threadid() is discouraged since Julia v1.10 because threads are no longer "sticky", meaning that tasks and threads can be detached in latest versions of the language: https://julialang.org/blog/2023/07/PSA-dont-use-threadid
We need to refactor the Interpolate and InterpolateNeighbors transforms to avoid rare race conditions.
