Description

As discussed in zulip, we want to make sure we don't have conflicting tagged-base64 tags. For this I've made espresso-systems-common

The #[tagged_blob(...)] macro did not support constants. This PR adds this, as well as a test to make sure the new derive macro actually works.

question: can you help me recall why this would print to this string? Why AAAAAAAAAABr ?

I believe AAAAAAAAAAB is the length of the buffer (0u64) and r is the checksum
