Daira Hopwood 59a220d59e Change the types of cm_x, Uncommitted^Orchard, and ak in Orchard to { 0 .. q_P-1 }, 
avoiding type errors and reflecting the implementation in zcashd. This eliminates all uses of P_x
(except that ak in an Orchard full viewing key is still required to be a valid Pallas affine
x-coordinate). Also clarify the coordinate system whenever we refer to coordinates.

also checking rt^Orchard \in P_x would require a square root and is unnecessary.

Daira Hopwood b7f0a0bd0d Correct a minor error in the proof of \theoremref{thmsinsemillacr}: 
the condition SinsemillaHashToPoint(D, M) ≠ ⊥ is required in the proof.
(The case SinsemillaHashToPoint(D, M) = ⊥ is covered by \theoremref{thmsinsemillaex}.)
The proof had not been updated correctly when the statement was revised in v2021.2.0.
Also add a missing D argument to SinsemillaHashToPoint in that proof.
