fix: don't shuf psk (#180)

Browse source 
- Shuffle Function will no longer shuffle PSK.
- Shuffle Function optimized.
- Fixed a bug in `FakePresharedKeyExtension` causing program to panic.
- Added `HelloChrome_100_PSK` and `HelloChrome_112_PSK_Shuf`. Both are beta fingerprints, use at your own risk.
