added option to set amount of mem used by the packer
lowered the default memory for the packer to 4g, pipeline still uses 16g
lowered the packer default slice size, reduced the default memory 16g --> 2g),
and made the memory amount an argument (--packer-mem)
Now exits with an error code if the packing failed. Also fixed a bug where it wasn't
heeding the command-line arguments.
Moved remove-unary-abstract filter to a more general rules-filter, and added scope-3
filtering of rules
added ability to trim tuning and test data (--maxlen-tune and --maxlen-test)
