1. go mod vendor
2. make all
3. ./bin/mixer

Please see comments in the code where I note potential issues/assumptions I made/future enhancements that could be made. The mixer service I created is running locally for the time being. I tried to break the problem up into chunks that lend themselves to containerization -- the mixer service, the client service, the dispatcher, etc. As of right now, I have no external storage system/database set up. The data saved during mixing dies along with the mixer service.

I provided three testing files clientlib/lib_test.go, mixerlib/lib_test.go internal/dispatcher_test.go for test coverage of some of the major functions used
