Support Execution from a Docker Container and Control Format Output Options

[AErmie]

It would provide more flexibility if this was made available through a Docker container, and also support StdOut output, along with a --format parameter.

Example:
docker run --rm -t -v $(System.DefaultWorkingDirectory)/DirectoryWithTAPFile:/src aghassemi/tap-xunit /src --format JUnit (or whatever other supported formats) > $(System.DefaultWorkingDirectory)/results.xml

My ultimate goal with this, is to covert the output from the GitHub Super Linter, into a supported format that can be then published as Test Results in Azure DevOps pipelines.
