Fix: Potential Vulnerability in bzip2 Library

[tabudz]

This PR fixes a security vulnerability in inflate() that was cloned from zlib but did not receive the security patch applied in zlib. The original issue was reported and fixed under https://gitlab.com/federicomenaquintero/bzip2/-/commit/74de1e2e6ffc9d51ef9824db71a8ffee5962cdbc.

This PR applies the same patch as the one in zlib to eliminate the vulnerability.
