Minor: Add aux constructor to PartitionedFile to avoid calculating size

[comphead]

Is your feature request related to a problem or challenge?

There bunch of places where

impl PartitionedFile {
    /// Create a simple file without metadata or partition
    pub fn new(path: String, size: u64) -> Self 

is used, it requires the exact size of file, otherwise it is a crash like

Error: ParquetError(General("AsyncChunkReader::get_bytes error: Generic LocalFileSystem error: Out of range of file /tmp/test/part-00000-dbdc88ee-c30e-4d2c-bef1-ee966702c2ae-c000.snappy.parquet, expected: 8, actual: 0"))

Describe the solution you'd like

Create an aux constructor to avoid file size calculation for the user.

Describe alternatives you've considered
