urllib.parse was unable to parse relative address

[donald001]

Describe the bug

net.urllib can parse absolute http URL, but failed to parse relative path.

Reproduction Steps

Here is the code:

import net.urllib
fn main(){
	u:=urllib.parse("https://vip.ffzy-online4.com/20230205/6094_d2720761/index.m3u8")!.resolve_reference(urllib.parse("2000k/hls/mixed.m3u8")!)!
	println(u.str())
}

Expected Behavior

Here is the java code:

System.out.println(URI.create("https://vip.ffzy-online4.com/20230205/6094_d2720761/index.m3u8").resolve("2000k/hls/mixed.m3u8"));

The url should be resolved just as the java result shows: "https://vip.ffzy-online4.com/20230205/6094_d2720761/2000k/hls/mixed.m3u8"

Current Behavior

We just got the error: "V panic: result not set (net.urllib.parse: failed parsing url (2000k/hls/mixed.m3u8))"

Possible Solution

fix the "parse" method
