POC Implement developer APIs about apple-private-apis

[f1shy-dev]

Dadoum's vision for the API/how it should look:

let account = AppleAccount::login(...ui handlers...)?;
let xcode_session = XcodeSession::with(&account)?;

let certificate = if let Some(cert) = keyring.contains("certificate thing") {
  cert
} else {
  let certificate = CertificateSigningRequest::new();
  let accepted_certificate = xcode_session.submit_csr(certificate);
  keyring.add("certificate", &certificate);
  accepted_certificate
}

let teams = xcode_session.list_teams();

xcode_session.new_app_id(teams[0], "com.sidestore.SideStore.DWFXTYIGS")?;
let provisioning_profile = xcode_session.get_provisioning_profile(teams[0], "com.sidestore.SideStore.DWFXTYIGS");```
