RasterSourceRDD resample + overview params missing
In the course of resolving pr #3200, a few small bugs were detected that could be traced back to the RasterSourceRDD. Various RasterSourceRDD creation methods exist (e.g. spatial and temporal), but there's no consistency in the usage of OverviewStrategy and ResampleMethod. The upshot of this is that OverviewStrategy and ResampleMethod instances that the user would like to use for selecting which overview to source and determining how to sample said source imagery are ignored
#3200 adds support for OverviewStrategy and ResampleMethod parameters to the RasterSourceRDD.spatial, RasterSourceRDD.temporal and RasterSourceRDD.apply methods. The other RasterSourceRDD methods still need to be addressed.
