Demos for API design now available for review (OTC)

[Hugo Landau]

As discussed at the previous meeting, the demos are now available for
review as a PR against the main OpenSSL repository.

This will probably not be merged before Tuesday but instead be discussed
at that point, so if possible, it would be helpful if OTC members have
read this PR before Tuesday's meeting, time permitting:

https://github.com/openssl/openssl/pull/17991

Of course, if people want to post their feedback on the PR, this is
also welcomed and will be processed as much as possible prior to
Tuesday.

Thanks,
Hugo Landau
