This PR adds a constrained string type for
HumanReadableIdentifiers
to be used foritem_id
s throughout. The exact parameters of these can be discussed, but for now, it restricts characters to alphanumeric with dashes and underscores, a maximum length of 16and minimum of 6(now removed - tbd).Unfortunately this type can only be properly used within a pydantic model at the moment (see linked discussion on pydantic repo in the code), which is hopefully good enough for now. Ideally we'd provide an endpoint that can validate these IDs for uniqueness and format without having to create the whole sample first.
Closes #228
