Reader features must not be present when minimum reader version = 1 or 2

[riziles]

Maybe I'm doing something wrong, but the error message said to report so here it is:

duckdb.duckdb.IOException: IO Error: Hit DeltaKernel FFI error (from: While trying to read from delta table: 'deltafiles/test/'): Hit
 error: 31 (InternalError) with message (Internal error Reader features must not be present when minimum reader version = 1 or 2. Thi
s is a kernel bug, please report.)

Steps to reproduce:

import duckdb
import deltalake as dl
import os
import shutil

if os.path.isdir("deltafiles"):
    shutil.rmtree("deltafiles")

ducktbl = duckdb.sql("select unnest(range(1,100)) a")

dl.write_deltalake("deltafiles/test", ducktbl, mode="overwrite")

ducktbl2 = duckdb.sql("select a * 10 as a from delta_scan('deltafiles/test')")

dl.write_deltalake("deltafiles/test", ducktbl2, mode="overwrite")

dl.DeltaTable("deltafiles/test").restore(0)

duckdb.sql("select * from delta_scan('deltafiles/test') limit 3").show()

... it works fine without the restore(0) bit

Thanks for reporting @riziles! I think this is a problem in the delta-kernel-rs library we use internally, I will forward the issue there.
