Make Uri parser more restrictive about hammock

[miciek]

@asoltysik Thanks! I think second option would be the best. I haven't used at scala-uri but it looks like it's way better than java.net.URI.

Looking at scala-uri it uses parboiled, which is a java library with scala wrapper. IIRC that makes it not an option as hammock is cross-published to ScalaJS.

Yeah, the idea behind creating our own was to have something that worked for both scalaJS & JVM (and potentially scala native)

OK, @asoltysik I think that the only way forward then is to improve existing parser :)
