Enable hiding commitments in nova and hypernova (#129)

Browse Source 
* feat: enable hiding commitments in nova and hypernova

* fix: set blinding values for witness vector

* fix: remove cloning of the cyclefold running instance

* fix: do not re-use blinding values between prove steps

* fix: specify whether the witness should use blinding values using a
const generic

* feat: create a `dummy` method for nova witnesses as well

* chore: clippy - removed unused imports
