 The assumptions of this module:
 - noir constraints are defined as a noir package in `./noir/crates/<constraint>/`
 - ./noir is relative to this file
-- noir constraints have already been compiled.
 
 For ergonomics, one should provide python wrappers that understands the API of
 the corresponding constraint.
