Support for nanoseconds in DateFormat

[GewuerzRegal]

Elasticsearch supports dateformats with nanoseconds, but spring data elasticsearch doesn't support this:
https://docs.spring.io/spring-data/elasticsearch/docs/current/api/org/springframework/data/elasticsearch/annotations/DateFormat.html
Could that be supported in the near future?
We need this to sort realtime events, there multiple events are inbound during the same millisecond.

Yes, for elasticsearch it's clear, that this is supported. But in spring data elastic there is no DateFormat like strict_date_optional_time_nanos so using spring the nanoseconds are rounded to milliseconds
