* build: use goreleaser to cross-compile binaries for all platforms and archs
The main motivation behind it is because "gox" is unmaintained and archived
and it does not support "linux/riscv64" as a target.
Right now, goreleaser is only building the binaries, and I've tried to replicate
the exact same way the old script does.
In the future, if so desired, goreleaser could be used to further automate the
build and release pipeline by creating the release in GitHub.
* build: create binaries and OCI image for linux/riscv64
The base directory has all shell scripts in scripts/
and all example/test files in examples/.
A Makefile provides all the commands with helpful information.
If a developer simply types `make` then vendor is properly updated,
the code is formatted, linted, tested, built, acceptance test run,
and installed.
Linting errors resolved.
Ignored test case (`TestParsePath`) updated to work as expected.
