Hi team,

I would like to request support for two features when fetching/parsing subscriptions:

1. **TCP Fast Open (TFO) for Shadowsocks (SS) protocol:** Ability to parse and enable TFO flags directly from the subscription links.

2. **“Allow Insecure” / Self-Signed IP Certificates without SNI for Hysteria 2 (HY2):** Support parsing and allowing connection configs that use `insecure=1` / self-signed certificates on pure IP addresses where SNI is absent.

Thanks for your hard work on this project!
