Copy files has more verbose logging
Added pipeline to drop mosaic images into one directory

Do not throw an exception if assemble produces no output.  Print log error instead.
Refactored pipeline manager to use a common function to iterate through child nodes of a pipeline.  It prevents a top level pipeline error from killing unrelated operations in later steps.
Use Nornir's implementation of stos-brute instead of ir-tools
Ensure meta data is saved if stos-brute runs
Renamed imageregistration.io package to 'files'
Support for new thread pool that distinguishes add_func and add_proc
version bump for imageregistration package
