Add nanosecond timestamp type

[NoldAndreas]

Feature Request / Improvement

Analogous to the update in apache iceberg from sep 3, 2024, include nanosecond precision for timestamps.

[MarkusMOtto]

This would be very helpful for high resolution time series data.

[Nicolas-SB]

Are there any updates regarding this topic? It would be quite important for our project to have more precise timestamps
