new: more parrots and safety update (#227)

Browse source 
* new: PQ and other parrots

Add new preset parrots:
- HelloChrome_114_Padding_PSK_Shuf
- HelloChrome_115_PQ
- HelloChrome_115_PQ_PSK

* new: ShuffleChromeTLSExtensions

Implement a new function `ShuffleChromeTLSExtensions(exts []TLSExtension) []TLSExtension`.

* update: include psk parameter for parrot-related functions

Update following functions' prototype to accept an optional pskExtension (of type *FakePreSharedKeyExtension):
- `UClient(conn net.Conn, config *Config, clientHelloID ClientHelloID)` => `UClient(conn net.Conn, config *Config, clientHelloID ClientHelloID, pskExtension ...*FakePreSharedKeyExtension)`
- `UTLSIdToSpec(id ClientHelloID)` => `UTLSIdToSpec(id ClientHelloID, pskExtension ...*FakePreSharedKeyExtension)`

* new: pre-defined error from UTLSIdToSpec

Update UTLSIdToSpec to return more comprehensive errors by pre-defining them, allowing easier error comparing/unwrapping.
