✨ Added 'Ripple' to the list of supported clocking schemes

[marcelwa]

Description

This PR introduces support for the Ripple clocking scheme proposed in this thesis. It is an older scheme and we are only supporting it for the sake of completeness. As it turns out, exact has severe issues realizing even the simplest of functions using this scheme. It is not advised to use it. Rather use 2DDWave or USE.
