without_files flag for RawDeltaTable

[MykhailoHevak]

There is the method without_files in the DeltaTableBuilder

delta-rs/rust/src/builder/mod.rs

Line 156 in c13804d

pub fn without_files(mut self) -> Self {

The method sets require_files flag in DeltaTableLoadOptions. And this flag is very useful cause it can load DeltaTable with significant memory reduction.

But python's class RawDeltaTable doesn't have the flag! And it is impossibly to handle tracking files :(

delta-rs/python/src/lib.rs

Line 105 in c13804d

fn new(

So, it's impossible to load big DeltaTable if python's library is used :(

Yes I think we could add a new flag to the DeltaTable constructor for that. Would you be willing to make a PR?

BTW, DeltaTable is the public class. RawDeltaTable is meant to be internal.

Sure, I will do PR
