Adjust root module code for github.com/olekukonko/tablewriter 1.x API

The API of the `github.com/olekukonko/tablewriter` module was completely redesigned prior to the 1.0.0 release. This
made it incompatible with the code written for the API of the 0.0.x versions of the module.

These code changes are purely refactoring. They do not result in any change to the output of Arduino Lint.

The previous version of `github.com/olekukonko/tablewriter` had a bug that caused it to incorrectly add a blank line
when the cell content contained an explicit line break. That bug has been fixed, and so the code previously required to
work around the bug has been removed.
