Make dive mode detection more advanced
In commit a09b1855d656, a RTE function was factored out, that was
used to detect dive mode vs. surface mode.
In the hunt for the time difference bug between stopwatch and dive time
some progress was made, but its still not totally right. Add some old
logic back, that seems reasonable.
A pool test after this commit shows some improvement, but still there
is some random difference between stopwatch and dive time. Things like
perfectly in sync for 20 min. surface shortly, and descend again in
the same dive. Now, the was a 1 or 2 second difference.
