feat: Breaking change: support conjunctions of disjunctions of conjunctions when requesting attributes in any of the three supported session types

Instead of requesting several attributes, one can now request several groups of attributes. Within each such group, attributes belonging to the same credential type always come from the same credential instance. This affects all three session types, as in each of them attributes can be disclosed.

Resolves #21

- Extract raw information from session, and only derive for display
- Add protocol version and ABS timestamps in log entries. Include an update function for existing logs
- AttributeValue of AttributeResult is now a TranslatedString
- Removed polymorphic 'response' from log entry; populate either IssueCommitment or Prooflist instead
- Greatly simplified marshalling log entries by not using a separate struct
- Added tests for disclosure logging

When parsing irma_configuration, we now check the timestamp of each scheme manager to decide if that manager must be copied out of the assets into storage, instead of the (scheme manager-transcending) file irma_configuration/timestamp.

Attributes may now also remotely be made optional.

This also required adding support for calculating the metadata version
based on the protocol version, and sending the current protocol version
to the server as a hint.
