Bug

What happened:

Sometimes duration fields suffixed with _ms report time as milliseconds (expected), but other times they are reported as microseconds.

https://github.com/delta-io/delta-rs/blob/main/crates/core/src/operations/update.rs#L400

https://github.com/delta-io/delta-rs/blob/main/crates/core/src/operations/delete.rs#L204

What you expected to happen:

All fields using _ms should be in milliseconds.

_ms -> milliseconds
_us -> microseconds

How to reproduce it:

More details:

Microsecond granularity is likely not needed for any operations that traverse the network.
