Calculate min_value and max_value metadata #8

Open dobesv opened 4 years ago

dobesv commented 4 years ago

When writing out parquet the min and min_value metadata can be used by a reader to skip row groups and even entire files. However, this metadata is not currently calculated by this version of the library.

It would be great to port over this feature from https://github.com/ZJONSSON/parquetjs

Would you accept a PR with this?
