filter not supported in read_parquet

[laygr]

If I do

using Parquet
filter = row -> row.some_column == "some_value"
Parquet.read_parquet(filepath, filter=filter)

I get the following error:
"Closest candidates are: Parquet.Table(::Any, ::Parquet.File, ::Tables.Schema; rows, batchsize, column_generator, use_threads) got unsupported keyword argument "filter""

But according to the README, filter is a supported option in read_parquet.
