Other discrepencies with 2.0 spec

Catch all for anything in the code needing to be caught up to on the 2.0 spec

selection sequence numbers should be sequentail in the contest.
"The first selectable option in the list has option index 1." (p.17)

Fixed in PR #378

Hashing strings (5.1.4)

"When an input to the function H is a string s, it is encoded as a byte array b(s, len(s)) using UTF-8
encoding. Here, len(s) is the length of the UTF-8 encoding of the string s in bytes."

But we are just using String.encodeToByteArray().

Works as long as we are consistent, but will break vs conformant implementation.

Affects

1. ContestData.encryptContestData()
2. KeyCeremonyTrustee.shareEncryption()
3. AddEncryptedBallot.closeChain()

Since ContestData format is not specfied, we will disagree with the rust library.
