Fallback 连接报错 handler not found

[wgjas2]

升级到0.5.0，已经无法正常使用VMessWSS，测试过0.4.0也不行，之前一直正常使用0.3.0（现在证书过期也装不上去了） 问题如下：

• 直连正常
• 需要通过代理的全部被断开，VS跟踪结果附在最后

配置文件如下：

[General]
# Log are for debug only
loglevel = trace
# Do not remove tun-fd option
tun-fd = 233
dns-server = 223.5.5.5, 114.114.114.114

[Proxy]
Direct = direct
Reject = reject

VMessWSS = vmess, ..., 443, username=..., ws=true, tls=true, ws-path=/...

[Proxy Group]
Fallback = fallback, VMessWSS, interval=600, timeout=5

[Rule]

EXTERNAL, site:category-ads-all, Reject

IP-CIDR, 8.8.8.8/32, Fallback
DOMAIN, www.google.com, Fallback
DOMAIN-SUFFIX, google.com, Fallback
DOMAIN-KEYWORD, google, Fallback

# 等效于 EXTERNAL, mmdb:us, Fallback
GEOIP, us, Fallback

EXTERNAL, site:geolocation-!cn, Fallback

FINAL, Direct

VS调试输出（Fallback部分）：

看起来是没有找到Fallback，不知道为啥

很遗憾地通知您，Leaf 核心在插件系统相关更改中移除了 VMess 支持，并且没有继续支持的计划。（见 https://github.com/eycorsican/leaf/issues/219 https://github.com/eycorsican/leaf/issues/201 ）这就导致包含 VMess outbound 的 Proxy Group 会被静默忽略。 目前，Maple 所依赖的修改版 Leaf 回滚了插件系统，并且重新启用了 VMess。请更新到 v0.5.1 再试一下。

非常感谢！经测试v0.5.1已经可以正常使用了，没想到VMess竟然被移除了……
