Update cf-edhoc and edhoc-rs

[actyp]

In order to overcome the failing tests, the edhoc-rs commit hash needed to be updated, which in turn required the update of the cf-edhoc library up to the latest version v23. So the changes are the following:

• Added supported protocol versions up to v23, which is the only one that required some changes in MessageProtocolPersistent

• Bumped the commit hash of cf-edhoc

• Bumped the commit hash of edhoc-rs to the latest one, which uses the latest changes from v23 and updated the args files

• Updated the saved model of server, which now contains one less state and updated the ci.yml

Changes are OK.

On a second thought, I am wondering whether it would be better to use the tag 0.5.0 instead of the commit hash for edhoc-rs (since this corresponds to a release). I will let you decide.

[actyp]

Yes it may be better, so I

• used the tag of edhoc-rs and
• updated the setup_fuzzer.sh and setup_sul.sh scripts with a slightly more flexible name of the checkout variable (in case we want to use other means to checkout the git repos).

Looks good. Go ahead and merge this.
