Description
### Describe the enhancement requested
I'm interested in interoperability with Arrow for systems that support picosecond precision timestamps.
Given the decreased range available in 64 bits, I think a 128 bit timestamp would be required. I propose a new timestamp128 data type that has support for picoseconds as a unit.
