parquet should depend on a small set of arrow features

[msalib]

parquet has an optional dependency on arrow. But when users do depend on parquet with arrow support, they get all of the default features for arrow, even though parquet doesn't need any of those features.

My project depends on parquet and needs the arrow feature as well, but this makes my build times very large since arrow has so many default features that I don't need.

I'd like to change parquet's optional arrow dependency to not depend on the full set of default features. This is a one line change!

My proposed fix is in #801
