Crow does not accept 0 MASK bit in websockets

[The-EDev]

Crow does not check the mask bit, instead it applies the mask regardless (since the mask is always 0 if the mask bit is not set), but this would still involve memory allocation, asio reading, and a loop containing XOR and MOD operations.

a better implementation would be to check the mask bit and ignore any operation if the bit isn't set.

Update: I was incorrect, crow just shuts the connection if the message is not masked. I'm almost sure this isn't how it should work, especially if we're using SSL
