feat: add meek

[AkinoKaede]

Background

Meek is a censorship-resistant protocol that encodes traffic into many plain HTTP requests/responses, and make the proxy flow characteristics more obscure. This PR implment Meek transport from V2Ray.

See https://www.v2fly.org/en_US/v5/config/stream/meek.html.

Proposed link format

VMess

V2RayN-like format

Use path for the url of Meek, and tls should be set to tls.

Example:

{
    "v": "2",
    "ps": "Meek",
    "add": "1.1.1.1",
    "port": "8000",
    "id": "21f2f2a0-3c25-4dec-5e8c-afc3f190e985",
    "aid": "0",
    "net": "meek",
    "type": "none",
    "tls":"none",
    "path":"https://dae.v2raya.org:8000/"
}

Share link is vmess:// + base64_encode(json)

Standard Proposal

see v2fly/v2ray-core#2638

VLESS Standard-like format

vless://[email protected]:8000/?url=https%3A%2F%2Fdae.v2raya.org%3A8000%2F&security=tls
