Cannot bypass the warning "could not mmap compressed IPC file, defaulting to normal read"

Polars version checks

• I have checked that this issue has not already been reported.

• I have confirmed this bug exists on the latest version of Polars.

Issue description

When polars reads compressed IPC files, it prints "could not mmap compressed IPC file, defaulting to normal read". As it cannot be bypassed, it is very disturbing when I read thousands of files.

Reproducible example

import pandas as pd
df = pd.DataFrame({"x": [1,2,3]})
df.to_feather("/tmp/example.feather")

import polars as pl
pl.read_ipc("/tmp/example.feather")

Expected behavior

There should be no warning.

Or, it would be good if the warning can be ignored with warnings.simplefilter(action="ignore").
