thread '<unnamed>' panicked at 'assertion failed: output.len() <= c_int::max_value() as usize

I've used your tool for over a year to extract my signal backups, and it always worked perfectly, it even managed to extract incomplete copies of *.backup files that I ended up with from time to time.

But now I ran into a problem:

13:52:56 [0m[34m[INFO] [0mOutput path: signal-2023-07-26-04-46-08 13:52:56 [0m[34m[INFO] [0mInput file: Archives/signal-2023-07-26-04-46-08.backup thread '' panicked at 'assertion failed: output.len() <= c_int::max_value() as usize', /root/.cargo/registry/src/github.com-1ecc6299db9ec823/openssl-0.10.38/src/symm.rs:627:13 note: run with RUST_BACKTRACE=1 environment variable to display a backtrace

I've tried to do a fresh install using cargo install --git https://github.com/pajowu/signal-backup-decode signal-backup-decode since I thought maybe there was something broken with the openssl (since that was what caused the panic), but today's stable rust compiler version doesn't want to compile the version in this git repository:

Next I've had a look at https://github.com/pajowu/signal-backup-decode/network and found a fork with a branch that had a promising name: support-new-backup-version.

I managed to install that version using cargo install --git "https://github.com/pascalgn/signal-backup-decode" --branch support-new-backup-version which also gave a few warnings, but no errors.

Using that I was able to unpack my newer signal backups just fine again. Would be lovely if you could merge that change and publish a new version with it.
