Updates lz4_flex from 0.13.0 to 0.13.1

Changelog

Sourced from lz4_flex's changelog.

0.13.1 (2026-05-09)

Fixes

• Fix compression with short dictionaries (less than 4 bytes), avoiding a panic/out-of-bounds read #222

Compression with dictionaries shorter than the minimum match length of 4 now falls
back to compression without a dictionary instead of panicking or reading past
the dictionary. 
This is a security fix for unsafe compression with untrusted dictionaries.

Users on 0.13.0 should upgrade to 0.13.1.

• Fix panic in From<io::Error> implementation for frame::Error #221 (thanks @​phoerious)
