API: `IdentityFileEntry.into_identity` and `.to_recipient` not accessible

I appears that IdentityFileEntry.into_identity and .to_recipient are pub(crate), so I can't use them in my own crate.

https://github.com/str4d/rage/blob/f84af2c069514ed61392597349d945680c51b074/age/src/identity.rs#L22

Is there a specific reason for that or could they be made pub?

[str4d]

The logic they implement can be implemented outside the age crate, because IdentityFileEntry is a transparent enum. That being said, they are nice helpers to have available. The only issue is that if the plugin feature is not enabled, it would be preferable to not require the callbacks argument, which makes the API a bit awkward to use, but that is still doable.

Hmm, this might end up interacting with the refactor I need to do as mentioned in https://github.com/str4d/rage/pull/334#issuecomment-1236127574. So while I can place the callbacks arg behind the plugin feature flag, I'll wait until I'm a bit further into #403 before working on this issue.

The refactor mentioned above is #504.
