slightly complicated by the fact that we have three different types of

The MPCORB ones are simplest; there's no header data. We just take a
line from file 0, then file 1, then file 2, ... file n_processes-1,
and repeat, writing them out as we go, doing a multi-way merge.
.sof files are almost as easy, except that there's a single header line.
So we skip the first n_processes - 1 lines read in, because they're all
header lines. Then we get a header line (and write it); then we start
reading in actual orbital element lines and write them.
'elements.txt' files, signified with skip_over == -1, mean that for each
file, we keep reading in lines until we hit the '# Sigmas avail" one.
We don't really care about that or anything after it. */
