WELSEGS and COMPSEGS carry a per-well header record followed by that
well's segment records, so segments from different wells cannot share a
single header. Commit 6ef024c merged records of the same keyword across
wells, which is invalid for these two keywords.
Accumulate WELSEGS and COMPSEGS as separate per-well blocks in a
dedicated container and serialise each block individually, while the
remaining keywords (WELSPECS, COMPDAT, WSEGVALV, WSEGAICD, well-control
and schedule keywords) continue to merge. Emission preserves the
existing priority ordering.
