Workspace Method abs_linesArtscat4FromArtscat3

Description

Convert a line list from ARTSCAT-3 to ARTSCAT-4 format.

ARTSCAT-4 lines contain more information than ARTSCAT-3 lines,
particularly they contain separate broadening parameters for six
different broadening species. So a real conversion is not
possible. What this method does is copy the air broadening (and shift)
parameters from ARTSCAT-3 to all ARTSCAT-4 broadening species. The
case that one of the broadening species is identical to the Self
species is also handled correctly.

The idea is that the ARTSCAT-4 line list generated in this way should
give identical RT simulation results as the original ARTSCAT-3
list. This is verified in one of the test controlfiles.

Currently only broadening and shift parameters are handled here. There
are some other additional fields in ARTSCAT-4, which we so far ignore.
