`--no-processes` does not work with `--snapshot`  or `--loop`

The recent updates make it much easier integrate `nvtop` with other software. Thank you!

It would be great if the snapshot and loop modes supported the `--no-processes` flag.

As of `3.3.2` these commands still show the `processes` array:

```bash
nvtop -sP
```

```bash
nvtop --snapshot --no-processes
```

```bash
nvtop -lP
```

```bash
nvtop --loop --no-processes
```
