[FEAT] Support FEP-044f

[AmaseCocoa]

Repository Check

• I have verified this is the correct repository for this feature
• This is NOT about HTTP signatures (should be in apsig repo)
• This is NOT about ActivityStreams models (should be in apmodel repo)

Feature Description

/#security-considerations
support FEP-044f

Motivation

for compatibility

Proposed Solution

fep-044f support

Alternatives Considered

Separate to another library

apkit.models employs a design that makes it easy to implement new models. Therefore, it might be the appropriate option if you need support for it. (That is, we don't actively support it.)

(In the first place, apkit is not designed to provide overly protective support to developers, so you may only need to do things like implement the model.)
