Use Taskfile for building Go code

Developers first used Makefile for Java, many years ago.  Then ANT came, and then settled with Maven.  Gradle came out, but Maven is still dominant.

With Go, developers using Makefile, saying the same thing when Makefile was used for Java - "It's good enough."

After some searching, found taskfile, written in Go.  It's easier and better than Makefile in many ways, and it's platform independent.  As Java building moved to Maven from ANT, there might be more advanced building tool in the future for Go, however, for now, Taskfile is a better alternative to makefile.
