sharkdp d43827fe57 Add --max-results=<count> option
This new option can be used instead of piping to `head -n <count>` for
improved performance:

| Command | Mean [ms] | Min [ms] | Max [ms] | Relative |
|:---|---:|---:|---:|---:|
| `fd --max-buffer-time=0 flow.yaml` | 153.9 ± 2.5 | 151.3 | 170.3 | 4.21 ± 5.86 |
| `fd --max-buffer-time=0 flow.yaml \| head -n 1` | 145.3 ± 17.4 | 111.0 | 180.2 | 3.98 ± 5.55 |
| `fd --max-results=1 flow.yaml` | 36.5 ± 50.8 | 7.2 | 145.7 | 1.00 |

Note: there is a large standard deviation on the last result due to the
non-deterministic file system traversal. With `--max-results`, we don't
have to traverse the whole filesystem tree, so it's all about luck.
