Package name: cihai[cli] -> cihai-cli (#326)

**#326, cihai/cihai-cli#279

The CLI version of `cihai` installed through `cihai-cli` again

Old (cihai 0.9 to 0.14, cihai-cli 0.5 to 0.10):

```console
$ pip install cihai[cli]
```

After (cihai 0.15+, cihai-cli 0.11+):

```console
$ pip install cihai-cli
```

This made deploying cihai + cihai-cli and pinning packages extremely laborious.

We can reinvestigate this model in the future.
