my.github: some work in progress on generating consistent ids

sadly it seems that there are at several issues:

- gdpr has less detailed data so it's hard to generate a proper ID at times
- sometimes there is a small (1s?) discrepancy between created_at between same event in GDPR an API
- some API events can have duplicate payload, but different id, which violates uniqueness
