New header parameters or facilities

A number of new objects have been added to the header in addition to all the previous ones.

- For the programmer convenience, 3 pointers to the `ref(:)`, `val(:)` and `inc(:)` values are now available, allowing easy writing of loops on the dimensions. They are real Fortran pointers to (and not duplicate of) the `convert` array from the coordinate section2.
- In the extrema section, the min and max value coordinates in the cube are coded in memory as a `MINLOC` and `MAXLOC` arrays with 7 elements. In the disk file, they are coded as 2 flat (scalar) address in the data.
- The Doppler factor (`dopp`) and the velocity type (`vtyp`) have been added to the spectroscopy section.
