Jukka Aho 72cb112ffe test(io): add postprocessing test
New 23-line test file for postprocessing functionality:
- Tests field interpolation from elements
- Tests temperature field interpolation on 1D segment elements
- Tests interpolation at various points including boundaries
- Tests NaN handling for points outside domain

Simple test validating postprocessing interpolation works correctly.
