A long overdue maintenance update that:

• Improves usability and performance of the support scripts
• Upgrades kcov and shellcheck tools to the latest version
• Cleans up and improves documentation
• Simplifies docker entry points
• Fixes CI pipeline

A quick bug fix, hot on the heels of the last minor release:

• Drastically reduced the size of the docker image
• Fixed broken file links in Codecov reports
• Running ./bin/docker from a branch will no longer override local copy of umkadk/getopts_long:latest
• Implemented shellcheck checks and fixes for all support scripts
• Re-enabled previously disabled tests

This releases focusses on upgrading getopts_long continuous integration environment.

It adds all of the following features:

• a local test environment provided by docker;
• support for shellcheck, bats, and kcov;
• shortcuts for docker and test commands (see ./bin);
• validation of the pushed code via GitHub Actions;
• integration with Docker Hub and Codecov.

It fixes a number of outstanding issues:

• test scrips are no longer dependant on git command;
• documentation has been updated to include better installation instructions.

getopts_long is a pure BASH "upgrade" on top of the built-in getopts. It is written in pure BASH, has no external dependencies, and provides support for GNU-style long options:

• --option
• --option value
• --option=value.

As of this release getopt_long is 100% compatible with the built-in getopts, and can be used as its drop-in replacement.

Command line parsing in bash scripts is rarely a simple job. The built-in getopts only supports single-character option, and I often find myself wishing for GNU style long options...

getups_long is an "upgrade" to the built-in getopts, which supports the following long options on top of everything the builtin getups already does:

• --option
• --option value
• --option=value
