Cannot parse searchParam that contain `=` in value

[xg-wang]

recognize ignores search param value after the =. For example this is reported in pretenderjs/pretender#316

let u = new URL('/films?filter=genres=in=(comedy);actor=="Ryan Reynolds"', window.location)
for (let pair of u.searchParams.entries()) {
   console.log(pair[0]+ ', '+ pair[1]);
}

// Browser output: 
// filter, genres=in=(comedy);actor=="Ryan Reynolds"

Line 719 in 8e2969b

parseQueryString(queryString: string): QueryParams {

appears to be supporting array syntax but it's something else https://github.com/tildeio/route-recognizer/blob/8e2969be64/tests/recognizer-tests.ts#L794-L803

Notice route-recognizer also does not allow recognizing with searchParams / qp #53.
