fix: ss obfsParams parsing index out of range
feat: support ss v2ray-plugin parsing
feat: support hy2 schema parsing

[H1JK]

Where is "hy2" used as the URL scheme for Hysteria 2? Any documentations?

@snakem982 Is this OK? fcdc47e
I think we should get plugin name from parsed arguments to avoid exceptions like plugin=v2ray-plugin;path=/obfs etc.

@snakem982 Is this OK? fcdc47e I think we should get plugin name from parsed arguments to avoid exceptions like plugin=v2ray-plugin;path=/obfs etc.

pluginInfo, _ := url.ParseQuery(strings.ReplaceAll(plugin, ";", "&"))
pluginName := pluginInfo.Get("plugin")

pluginInfo does not contain the field plugin
So it cannot be modified like this

How about add "plugin=" to the start of the string? Or any other solution for this? 🥲

If the URL is like this plugin=urlEncode(path=/obfs;v2ray-plugin;)
This won't work

[H1JK]

plugin=urlEncode(path=/obfs;v2ray-plugin;)

Is this legal, anyway?

SIP002 says plugin is encoded "the similar format" as "TOR_PT_SERVER_TRANSPORT_OPTIONS". And it is:

Specifies per-PT protocol configuration directives, as a semicolon-separated list of : pairs, where is a PT name and is a k=v string value with options that are to be passed to the transport.
Colons, semicolons, and backslashes MUST be escaped with a backslash.
If there are no arguments that need to be passed to any of PT transport protocols, "TOR_PT_SERVER_TRANSPORT_OPTIONS" MAY be omitted.

Example: TOR_PT_SERVER_TRANSPORT_OPTIONS=scramblesuit:key=banana;automata:rule=110;automata:depth=3

Will pass to 'scramblesuit' the parameter 'key=banana' and to 'automata' the arguments 'rule=110' and 'depth=3'.

The plugin name, however, is a anonymous-like argument and I don't think it is possible to appear in any other positions except the head.

Read the document information
Adding "plugin=" at the beginning is a good choice.

Merged. Thanks! 🎉
