Check in code changes that check for incompatible layout and filter options when parsing the command, avoiding a failure later on when the new dataset is created
COMPACT layout has a builtin maximum size in HDF5 and should not have a minimum size applied.
Datasets specified by name for --layout or --filter options will not have minimum size applied.

Tested with gcc and icc on 32bit and 64bit Linux (jam and platypus)
