Revisions (#4) 

* area should be 1 for all LUTs

* clean up macros

* add log_assert to fail noisily when encountering oddly configured DFF

* clean help msg

* flatten set to true by default

* update

* merge mult tests

* remove redundant test

* move all dsp tests to single file and remove redundant tests

* update ram tests

* add more dff tests

* fix c++20 compile errors

* add option to dump verilog

* default to use abc9

* remove -abc9 option since its the default now
