Move FieldTimeSeriesCollector to Oceananigans?

[glwagner]

Over in OceanTurbulenceParameterEstimation we've developed a utility called FieldTimeSeriesCollector that can be used in a callback to "collect" field data on the fly while a simulation is running. This is useful for idealized problems and quick experimentation where saving data to disk is unnecessary:

https://github.com/CliMA/OceanTurbulenceParameterEstimation.jl/blob/a05d1d8959ef40f0f3e7873b32caf4271f102592/src/Observations.jl#L257-L308

It'd probably be nice to move this feature into Oceananigans proper at some point so it's more visible and more people can benefit. And we can tweak the design / interface too. Because "field_time_serieses" (a NamedTuple collection of FieldTimeSeries) doesn't quite roll off the tongue.

I'm closing this issue because I'm judging that it's not of current, timely relevance to Oceananigans development. If you would like to make it a higher priority or if you think the issue was closed in error please feel free to re-open.
