Make it possible to override the default chunking behavior when loading to
daskarrays. ForPIConGPUthe default creates a chunk for each GPU with its local domain. When using static load balancing withgridDistinPIConGPU, this results in very uneven chunks. It looks like, for many operations, it makes sense to chunk along the outermost direction only (reading contiguous domains is faster). With this PR this can be achieved with.to_daks_array(chunks={0 : 'auto', 1: -1, 2: -1})
