txscript: Optimize CalcMultiSigStats.
This converts the CalcMultiSigStats function to make use of the new
extractMultisigScriptDetails function instead of the far less efficient
parseScript thereby significantly optimizing the function.

The tests are also updated accordingly.

The following is a before and after comparison of analyzing a standard
multisig script:

txscript

Build Status ISC License GoDoc

Package txscript implements the Decred transaction script language. There is a comprehensive test suite.

This package has intentionally been designed so it can be used as a standalone package for any projects needing to use or validate Decred transaction scripts.

Decred Scripts

Decred provides a stack-based, FORTH-like language for the scripts in the Decred transactions. This language is not turing complete although it is still fairly powerful.
