include base64url-encoded unpadded nonce in ChallengeResponseSession #45
Description
After this change: veraison/services#428, the nonce returned in a challenge-response session is base64url-encoded and without padding. The ChallengeResponseSession nonce may be updated to:
#[serde_as(as = "serde_with::base64::Base64<serde_with::base64::UrlSafe, serde_with::formats::Unpadded>")]
nonce: Vec<u8>,Edit: Added the Unpadded attribute after a quick look at the new cha-res spec in veraison/docs.
