Just a small derive_like macro that can be used to generate the key identifier enums. Example usage:

use bitwarden_crypto::key_ids;
key_ids! {
    #[symmetric]
    pub enum SymmKeyId {
        User,
        Org(uuid::Uuid),
        #[local]
        Local(&'static str),
    }

    #[asymmetric]
    pub enum AsymmKeyId {
        PrivateKey,
    }
    pub Ids => SymmKeyId, AsymmKeyId;
}
