73aaf4ecf8 Make SignatureExtractorChecker private to its own file (Ben Woosley)
Pull request description:
~If we add a CTxIn constructor to SignatureData, then constructing the
SignatureData directly is no more verbose than calling DataFromTransaction,
and grants the caller additional flexibiliy in how to provide the CTxIn.~
A simple change to enhance encapsulation.
