Dials

* dials.detect_blanks is now less conservative
* dials.scale fixes
* Updates to support Eiger stream data
* Updates to support Fast DP v1.1

* `dials.compute_delta_cchalf`: new utility to implement a delta-cc12 analysis for removing scaled data sets with poor agreement.
* `dials.export` can now export MTZs of single-image data sets.
* `dials.frame_orientations`: new utility to output a table and plot of crystal orientations for each image expressed as a zone axis direction.
* `dials.reindex`: allow reindexing against a reference file to give a common indexing between data sets.
* `dials.scale`: Addition of weak B-restraint for physical model to improve refinement stability. General bug fixes and stability improvements. Addition of cross validation options for scaling.
