We can now generate part families.

- README: added build prerequisites
- "part name" is now more correctly called "package name"
- changed keyword "part" to "package"
- removed inst_debug and struct inst_ops.debug functions - never really used 
  them anyway
- we can now generate multiple packages from a single file
