Write a results object in a file in the GEOMS format
This is done in multiple steps: 1. Constant values are written 2. Dimensions and their coordinates are written 3. Data arrays are written 4. File metadata is written
Create the named dimensions that will later be used for arrays in the dataset
Each dimension has a unique name and is just an integer number describing the size
Also each dimension has coordinates, which are also set here as a 1D Array of the size of the dimension with the proper values
Convert datetime object to modified julian date 2000.
According to GEOMS documentation
The Modified Julian Date, MJD2K, used throughout this document is defined as follows: MJD2K is 0.000000 on January 1, 2000 at 00:00:00 UTC
