Simplified infering arrow schema from a parquet schema

[jorgecarleitao]

Doing so no longer returns an error in reading unknown logical or converted types and instead simply falls to the natural type (e.g. an int64 parquet type with an unknown logical type is read as DataType::Int64)

Backward incompatible

• Function to do this was renamed from io::parquet::read::get_schema ro io::parquet::read::infer_schema
• Function no longer errors on unknown parquet logical types; only on unreadable arrow schema declared in the ARROW:schema
