cst-signer: init at 7fa50daf

The CST signer tool works in conjunction with the Code Signing
Tool (CST) provided by NXP. The tool allows a way to automate the
signing process in conjunction with a configuration file that can be
populated with necessary inputs. In addition, this tool parses the 'to
be signed' image and extracts the offset and length information needed
to sign the image, thus reducing the possible human error while signing.
