[feat] engines: add searchzee engine (general, news)

The results seem to be from Brave (i.e. they are exactly
the same). But it doesn't have any strict rate-limits,
so that's nice.

News support time ranges, but apart from that, unfortunately it doesn't
support any advanced features like safesearch or languages.
