Swap name and tagname for grids

Solves (?) #101

[equinor-ruaj]

This probably also swaps name <-> tagname in file.relative_path...
Not sure if that breaks anything or will just "look weird" to users?

The order in the filename should be the same as for other data types, I think.

Agree that there should be consistency across data types and contents. But we also know that there isn't necessarily full consistency in the currently used standard which this tries to emulate. So probably not possible to 100% win.

If possible, we could try to produce a case or two with this update to dev and have a look. I think the data browser in the Sumo front-end will quickly reveal if this is more, or less, chaos.

Separated metadata functions so "file.relative_path" should be set same as before. b8c05cf

Uploaded two Drogon cases to dev.
Left: Using this branch
Right: Using Sim2sumo main branch

name and tagname is swapped as intended.
file.relative_path is the same in both.
The rest of the metadata is also the same in both cases.

Other datatypes are unchanged.
