Jack Grigg c08d12cc52 Use incomplete addition in SinsemillaHashToPoint 
This requires exposing the ⊥ case throughout the return types. We
prevent it from propagating into the Orchard note and key types by
ensuring that:

- When we generate keys or notes, if we encounter ⊥ we discard and
  re-generate.
- When we construct keys or notes via any other pathway (e.g. parsing
  from bytes), we check for and reject ⊥.

Jack Grigg 907ff46078 Simulate incomplete addition 
Sinsemilla will use incomplete addition inside the circuit for
efficiency, but the pasta_curves crate uses complete addition.
