`noai` is a small CLI for re-encoding images through JPEG and PNG.
```bash
noai image <file-or-directory>
noai image -r <directory>
```
Output files are written next to the source file as `noai_<source-name>.png`.
If that filename already exists, `noai` keeps the existing file and writes to
`noai_<source-name> (1).png`, `noai_<source-name> (2).png`, and so on.
