Bug fixes:
- Fixed a typo in the meson.build files that was not caught by meson, due to a bug in meson's option handling.
- Versions of meson < 1.8.4 suffered regressions in option handling that were fixed in v1.8.4.
- Attempting to build Raysect with meson v1.8.4 resulted in an error.
New:
- Added pickle support to Interpolator1DArray, Interpolator2DArray and Interpolator3DArray.
