Automatically calculate certificate thumbprint

[hrumhurum]

sign requires a certificate thumbprint to be explicitly specified in the command line:

Usage:
  sign code certificate-store <file(s)>... [options]

Arguments:
  <file(s)>  File(s) to sign.

Options:
  -cfp, --certificate-fingerprint <certificate-fingerprint> (REQUIRED)   SHA fingerprint used to identify a certificate.
  -cf, --certificate-file <certificate-file>                             PFX, P7B, or CER file containing a certificate and potentially a private key.
  -p, --password <password>                                              Password for certificate file.
  -csp, --crypto-service-provider <crypto-service-provider>              Cryptographic Service Provider containing the private key container. Requires /k and optionally /km.
  -k, --key-container <key-container>                                    Private key container name.

However, when a certificate file is specified with -cf ( --certificate-file) option, it already has all the information to calculate its thumbprint. In this case, -cfp (--certificate-fingerprint) option should not be obligatory.

The current behavior requires a user to always specify -cfp (--certificate-fingerprint) option, even when the certificate file is specified explicitly. This adds certain frictions to sign usage as the user now has to manually extract/calculate the certificate fingerprint, even when it isn't strictly needed and can be extracted from the specified certificate file automatically.
