Bug: stt complains libbz2.so.1.0 not found

[alanorth]

Describe the bug Python stt 1.4.0 from pip crashes due to missing libbz2.so.1.0 on CentOS Stream 8 and probably all RPM-based distros:

$ stt
Traceback (most recent call last):
  File "/tmp/venv-test/bin/stt", line 5, in <module>
    from stt.client import main
  File "/tmp/venv-test/lib/python3.9/site-packages/stt/__init__.py", line 23, in <module>
    from stt.impl import Version as version
  File "/tmp/venv-test/lib/python3.9/site-packages/stt/impl.py", line 13, in <module>
    from . import _impl
ImportError: libbz2.so.1.0: cannot open shared object file: No such file or directory

But bzip2 libs are installed:

$ dnf list installed bzip2\*
Installed Packages
bzip2.x86_64                                         1.0.6-26.el8                         @baseos
bzip2-devel.x86_64                                   1.0.6-26.el8                         @baseos
bzip2-libs.x86_64                                    1.0.6-26.el8                         @baseos

And libbz2.so is available, albeit as libbz2.so.1:

$ ldconfig -p | grep libbz2
        libbz2.so.1 (libc6,x86-64) => /lib64/libbz2.so.1
        libbz2.so.1 (libc6) => /lib/libbz2.so.1
        libbz2.so (libc6,x86-64) => /lib64/libbz2.so

To Reproduce Steps to reproduce the behavior:

1. Run the following command pip install stt in a virtual environment
2. Run the following command stt
3. See error

Expected behavior stt to not crash.

Environment (please complete the following information):

• OS Platform and Distribution (e.g., Linux Ubuntu 16.04): Linux CentOS Stream 8
• Python version: 3.9

Additional context

I can make a symlink to fix this, but it feels dirty. I'm wondering which systems does this work on? Could stt check for libbz2.so.1 instead, or after checking for libbz2.so.1.0?
