Will sync with https://github.com/apache/arrow-rs/pull/1320 and update the test after its merge.

#1320 has been merged FYI

[alamb]

Looks good to me -- thanks @shanisolomon

cc @sunchao (mostly for visibility that the Rust implementation is beginning down the path of using more advanced parquet metadata features)

[shanisolomon]

Thanks, @alamb! Could you help with merging please?

[sunchao]

Thanks @alamb @shanisolomon ! yes it certainly will be VERY useful if parquet-rs has these advanced predicate pushdown features!

[sunchao]

Just merged to master!
