autoSHARP conversion of MTZ files to *.sca format for SHELXC/D

When starting autoSHARP with MTZ files, the automatic conversion to *.sca (SCALEPACK) format as needed by SHELXC/D can sometimes fail. This has to do with the determination of the appropriate scale to fit a general floating point number into a fixed width format. This will be fixed in the next release.

A current workaround is to start autoSHARP directly from *.sca files - as e.g. produced by running autoPROC.
