Failed to import ss:// (ssurl bug or Android app bug?)

[brianwoo]

Please read contributing guidelines. Thanks.

Describe the bug
Unable to import ss:// into the Android App. I am unsure if this is a ssurl bug or the Android app.

To Reproduce
Steps to reproduce the behavior:

1. Generate a password with ssservice genkey

/opt/shadowsocks/ssservice genkey --encrypt-method "2022-blake3-chacha20-poly1305"
F6BY4IwbXB5Juobo2aofoJ6P86G/yBYJO3pJzcMIUOU=

2. Create a json file with all the configuration

cat ~/Downloads/client.json 
{
  "server": "1.2.3.4",
  "server_port": 8400,
  "password": "F6BY4IwbXB5Juobo2aofoJ6P86G/yBYJO3pJzcMIUOU=",
  "method": "2022-blake3-chacha20-poly1305"
}

3. Encode the json to an ss:// string

/opt/shadowsocks/ssurl --encode ~/Downloads/client.json
ss://2022-blake3-chacha20-poly1305:F6BY4IwbXB5Juobo2aofoJ6P86G%2FyBYJO3pJzcMIUOU%[email protected]:8400

4. If I import this ss:// string into the Android app, I get an error "Failed to import."

5. If I decode the ss:// string (notice the password has a backslash for escaping the forward slash):

/opt/shadowsocks/ssurl --decode ss://2022-blake3-chacha20-poly1305:F6BY4IwbXB5Juobo2aofoJ6P86G%2FyBYJO3pJzcMIUOU%[email protected]:8400
{"server":"1.2.3.4","server_port":8400,"password":"F6BY4IwbXB5Juobo2aofoJ6P86G\/yBYJO3pJzcMIUOU=","method":"2022-blake3-chacha20-poly1305","mode":"tcp_and_udp"}

Expected behavior
ss:// string should be imported, even with an escape char in the json

I faced the same problem with others AEAD 2022 encryption methods. Without it, it is impossible to use the feature "one port -multiple users".
