What's Changed
* Interaction with RMS (Roxar API) is updated, https://github.com/equinor/xtgeo/pull/787, but only for Roxar API version 1.6 and later (i.e. RMS 13 and later):
* * RegularSurface (maps) can now read/write RMS `General 2D Data` and also the `Trends` container
* * Points and Polygons can now read/write RMS `General 2D Data`
* * Reading and storing Points attributes will be much faster vs roxar (using internal API upgrades in Roxar API from Roxar API version 1.6)
* * If a and xtgeo 3D grid contains subgrids, these will now be stored in RMS
