mupp v0.0.2

• Updated LICENSE to MIT to make publishing on Github/CRAN easier in the long run.
• Updated infrastructure to: 1) add Github workflows for "check-release", "pkgdown", and "test-coverage"; 2) add lifecycle stages for the overall package; 3) add code coverage; and 4) include badgets for CRAN check, lifecycle, and code coverage.
• Fixed overall documentation and standardized package documentation.
• Fixed test cases by adding seeds to reduce random noise, and fixed some style issues.
• cpp_profiler_tools.cpp removed due to compilation issues on remote systems.
