feat: Convert raw bytes or tlsfingerprint record to ClientHelloSpec (#168)

* feat: byte to clienthellospecs conversion

* feat: specific case for GREASE and ALPS

Will automatically add "h2" to ALPS and write to log when GREASE extension is imported in `ImportTLSClientHello()`

* fix: ReadCompressionMethods

ReadCompressionMethods didn't advance the s and fails reading extensions

* fix: remove debug log

* fix: use cryptobyte for internal helper

`helper.Uint8to16()` now calls `(*cryptobyte.String).ReadUint16()`

* fix: preshared key fingerprinter test

updated fingerprinter test to test with PreSharedKey extension

* fix: naming of FakePreSharedKeyExt

It is a Fake extension since `crypto/tls` doesn't really implement PSK-based resumption and neither do we.

* feat: Properly check GREASE

Adopted from #148.

* feat: add fakeExtensionEncryptThenMAC

And reordered `fakeExtensionDelegatedCredentials`.

The new `Fingerprinter` is expected to account for the `fakeExtensionEncryptThenMAC` using a `GenericExtension` when `allowBluntMimicry` is set.
