Hyphens, i.e. - in a query parameter name raise an exception.

Using this library to parse a template results in the following error:

Failed to parse URI template: /api/versions{?api-version}
 Error: SyntaxError: Expected "(", "*", ",", ":", "}" or [a-zA-Z0-9_.%] but "-" 

I'm happy to provide more information if necessary, but a cursory glance at this repo makes it seem like adding - to https://github.com/grncdr/uri-template/blob/master/index.pegjs#L22 would resolve this.

Please provide a reference to RFC 6570 where hyphen is specified as a valid parameter character. I don't see it.

It's a part of the unreserved set:

unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"

https://tools.ietf.org/html/rfc6570

[andreineculau]

unreserved is irrelevant. Meanwhile I looked at RFC 6570 myself.

     variable-list =  varspec *( "," varspec )
     varspec       =  varname [ modifier-level4 ]
     varname       =  varchar *( ["."] varchar )
     varchar       =  ALPHA / DIGIT / "_" / pct-encoded

varchar says "-" is not a valid parameter character. Closing, and apiaryio/dredd#460 should be closed as well IMO.
