There was a problem hiding this comment.
This is a lot of syntactic sugar to make enums reusable and less dependent on underlying (native) types. Also lots of type checkings checks when converting.

Currently, in the
C2paSignerInfoclass, we expected the algorithm string as bytes.As reported in #135, I believe it makes sense to allow to use the enum and that we parse it accordingly into the value needed by the native call.
This PR adds support for that, and also makes sure the timestamp URL gets properly converted into bytes since natively we expect bytes too.
