Jack Grigg 736de1156b Ensure that Notes always have valid commitments

if a note is generated without a valid commitment.

Jack Grigg a564ba76ce Remove Chain and value::Constraint traits 
There was push-back on having this crate require these traits, due to the
additional complexity within this crate. My rationale for including them
was to make it simpler to reason about what is responsible for enforcing
chain-specific constraints, and to reduce duplication (by enabling the
wrapping chain implementation to use type definitions and leverage all
built-in behaviour, instead of newtypes and needing to add a bunch of
wrapping logic and boilerplate, some of which would encode chain-specific
logic).

We'll try working within the requirement that this crate enforces minimal
base constraints and hard-codes any constants, and then have the wrapping
chain provide encoding prefixes and additional value constraints where
necessary.
