This is a follow-up of 3cd1253. A C++ program was written to automate the license update originally. That program was translated to Python so it can be kept in the repository and run when needed. It has been tested on Windows using the standard Python 3 installation and on Linux.
The original version skipped files that had "//" at the beginning since most were files that should be excluded. The relevant files are now in an exclusion list and the rest are processed normally. The .hpp file extension has been added as well. The script rewrote CompressorJNI.cpp to remove the carriage returns from its line endings.
Rename the following folders:
hal/lib/Athena -> hal/lib/athena
hal/lib/Desktop -> hal/lib/sim
hal/lib/Shared -> hal/lib/shared
wpilibc/Athena -> wpilibc/athena
wpilibc/simulation -> wpilibc/sim
Windows users may need to run gradlew clean after updating.
