Update ESLint and tap to quell warnings from `npm audit` and the
GitHub interface.

ESLint update required some changes to other files as indentation rules
are now more strictly enforced.

I'm seeing tests failing locally but that was the case before I updated
anything too, so hopefully this passes on Travis-CI or whatever.

chore: Update dependencies

In windows, assigning a port may take a little longer than previously assumed value of 2000ms.
I am using Windows 10 1903 64bit, and it takes about 3000ms to initialize a port.
I increased the timeout to some higher value (9999ms) to give a little more space to Windows to initialize a port to use with the app.

This patch probably solves issues #48, #54 and #70

This reverts commit b4d3c1a,
as it significantly broke the test suite.

fix: Revert "chore: Update dependencies"

Add a workflow to run tests with GitHub Actions.

[WIP] chore: Test with GitHub Actions

This is deprecated and emits a warning with `--pending-deprecation`.
I’m afraid I’m not familiar enough with this code to provide a test,
unfortunately.
