This PR adds the mssql_cbt module used to check whether Channel Binding is required or not.

IMPORTANT: this PR requires fortra/impacket#2098 being merged as I need to be able to inject a fake CBT value to test whether authentication works or not.

Note that CBT cannot be computed on local_auth or if TLS is not enforced (which explains the two first if else).
