Fix merge: assign cell measures and ancillary variables to correct dimensions

[rcomer]

🚀 Pull Request

Description

Fixes #2076

The problem was that merge tries to add the cell measure to the same dimension that it had on the input cubes. This is wrong, because the new dimension[s] are added to the start. So we need to add an offset in the same way that is already done for coordinates. The problem was not picked up by the tests because the output cube there was square (2 by 2) and there was no check for which dimension the cell measure was on. By adding a third cube in the test input, we reproduce the error shown in the issue.

Also made equivalent change for ancillary variables.
