David Howells 4c0b4b1d1a pefile: Parse the "Microsoft individual code signing" data blob
The PKCS#7 certificate should contain a "Microsoft individual code signing"
data blob as its signed content.  This blob contains a digest of the signed
content of the PE binary and the OID of the digest algorithm used (typically
SHA256).
