Using the previously implemented loader pattern, support on demand loading of observation data when accumulating hits, inverse covariance, and noise weighted maps for each observation. - Add PipelineLoader class, which implements a loader which runs a Pipeline to generate data for an observation. This can be used to simulate data on demand, one observation at a time. - Add AccumulateObservation operator, which can accumulate and cache or load per-observation map domain products. This allows building RHS map domain objects without keeping all detector data in memory, and also allows computing the RHS on smaller jobs which are I/O bound. - Change the BinMap operator to use this new accumulation technique. Use new pixel io interfaces WIP porting mapmaking utils to new accumulation Large WIP on per-obs accumulation with optional cache and load.
