- when an episode/report step is over, the next is started by endEpisode()
- the problem does not deal with updating the simulation time anymore
- rename `episodeIdx` in to `reportStepIdx` the 'EclWriter' because
this variable is -- and always has been -- the report step number
used by some parts of `opm-output`'s ECL writing code (the report
step number is equivalent to the episode index plus 1). IMO, the
output and parser code should be made more consistent in regard of
whether it expects 0-based or 1-based indices, but this is a story
for another day.
this is only relevant people who are masochistic enough to go beyond
`-Wall`. (note that at this warning level, there is plenty of noise from
Dune and other upstream dependencies.)
this leads to crashes deeply inside libecl. My cursory hypotheses are
that this test makes the assumption that the output is written
synchronously (it tries to read back the results from disk
immediately) and/or that libecl is not threadsafe.
