Added CI/CD.

build notes

Set up environment:

# for running tests
sudo apt-get update
sudo apt-get install libgtest-dev

mkdir build
cd build && cmake ..

Install Google Benchmark. Then you have 2 options for builds:

# ensure you are in build directory

# default standard (slow run) build
cmake --build .

# for long runs
cmake --build . --config release

Then when running the executable:

./main > img.ppm
eog img.ppn
