This updates the licenses script to pull in all PackageInfo.json files with a specific argument, then follows each license file defined and writes the contents to a file. In this mode, if a packageinfo file is found, it will only grab the license file path defined within.
Also has the following features:
* Generalizes the function and variable names for non-license specific references
* Sorts os.walk to maintain consistent ordering
* Uses an ordered dict for the output, also to maintain ordering if using Python below 3.7
* Adds an additional json config file to have specific exclusion rules for 3p packages
* Adds a package creation function and config file entry
* Allow multipath scans, optional use of gitignore, merged license file scan
