(‼) subprocess-tee is not a drop-in replacement for subprocess

It uses shell by default:
```py
from subprocess import run
from subprocee_tee import run as tee

tee("echo 1")  # 1
run("echo 1")  # FileNotFoundError: [Errno 2] No such file or directory: 'echo 1'
```

Either changes should be made to be consistent with `subprocess`, or the branding should be changed.
