Pass --no-init on Windows if less version < 559

We used to call `less` with
``` bash
less --RAW-CONTROL-CHARS --quit-if-one-screen --no-init
```
We only passed `--no-init` because there was a bug with previous versions
of `less` which required the use of `--no-init` in combination with
`--quit-if-one-screen` to prevent this "no output" issue from happening.

Since bat 0.13, [we omit the `--no-init` option](0ecc94956b/src/output.rs (L85-L97))
if we can detect that the version of `less` is higher than or equal to 530. We
did that because `--no-init` breaks mouse support and because [less 530 fixed
the above-mentioned bug](http://www.greenwoodsoftware.com/less/news.530.html).
However, it seems that this bug was *not* fixed on Windows!

According to @gwsw, the issue should be fixed with less 559 on Windows.
