Align TRUST_TOKEN_pst_v1_voprf with draft-21 of VOPRF

This aligns the DLEQ proof portion of TRUST_TOKEN_pst_v1_voprf
with draft-irtf-cfrg-voprf-21. The blind and finalize operations
still differ. Additionally, as VOPRF doesn't include batched
issuance, the issuance process around the DLEQ proof is adapted
from draft-robert-privacypass-batched-tokens-01.
