Appears on include guard instead of class
Avoids rewriting time-independent data, gives slight performance boost
Also remove deleted options!

Sort of fixes #2878
Two things:
output:flush_frequencycan be used to reduce how often netCDF data is flushed to disk (maybeflush_periodis a more accurate name?)Optionsused to store data to be written to disk is now reset after writingThese two together can significantly cut the time spent in IO:
(absolute time from the
iotimer forconductionexample for 500 timesteps, rolling average over 100 steps)The red line is basically current
nextI'm a bit concerned that we still get an increase over time, but this seems to unavoidable.
This PR also includes some drive-by fixes for some minor
OptionsIOissues.
