What's Changed
* Mostly kerchunk improvements by kthyng in https://github.com/axiom-data-science/particle-tracking-manager/pull/27
* Added utilities to generate kerchunk files on the fly for the time period of the simulation length for CIOFS and NWGOA. This has majorly sped up CIOFS simulations and modestly sped up NWGOA simulations.
* depth z should be negative! Fixed this in tests.
* added `start_time_end`, which adds OpenDrift capability for starting drifters over linear time frame
* fixed so unique log file is output for each simulation even if run in a script, and has the same name as `output_file`.
* small fix to histogram plot
