The code size is larger than 1mb, which is larger than the allowed size for viewer event in cloudFront

Hi,
The code size is larger than 1mb. which is larger than he allowed size for viewer event in cloudFront.
I followed some of the steps outlined in [issue 47](https://github.com/aws-samples/lambdaedge-openidconnect-samples/issues/47) which reduced the size a little bit but not enough. As in, i deleted all the `*.d.ts, *.txt, licese` which got it to 1.1mb but still need to reduce the size even more.

The deployment works when we use SAM to deploy. But when i try to manually zip up the `build` directory, the size is larger than expected.

Any suggestion to get over this issue?

Beginne mit dem Vergleich des SAM-Deployment-Pakets mit einem manuellen zip des Build-Verzeichnisses und verwende dabei das Größenlimit sowie die Bereinigungsschritte aus Issue 47 als Kontext. Ermittle, was im manuellen Archiv verbleibt, und dokumentiere eine reproduzierbare Änderung an der Paketierung, durch die es unter das CloudFront viewer-event-Limit fällt; verifiziere beide Deployment-Pfade.
