Add option to display line numbers that weren't executed

[flaeppe]

I took a swing at #16, displaying lines that weren't executed (uncovered lines) in the markdown table.

Added an option show_missing (default=false) for a column inclusion.

Although this doesn't include any fancy pants tracing of lines during branching
(e.g. misses on "jumps" that coveragepy outputs as: 22 -> 45)

Anyhow, let me know what you think. Great package. Thanks.

It'll need a rebase and a npm run package to make the checks ✅

Just some nitpicks

Thanks for the review.

Seems that a coverage check is failing. Looks like it fails on parsing my new show_missing variable. Am I interpreting it correctly that a GitHub environment is missing the variable? It's set as required: true. If that is the case, maybe we should make it required: false for backwards compatibility? (Can't remember if GitHub actions is forcing you to explicitly set a version when using an external action package)

I get a YAML validation error on line 31 when I run it through a validator. Maybe some weird white space?

did not find expected key while parsing a block mapping

Read the file name in the error a bit too quickly, was looking in the wrong file. There was a misplaced escape character on the failing line.

Really awesome work! 💯

Just double-checking, did you run npm run package after the last changes? (Would be sweet if we could automate this.. At least it's better than keeping node_modules under version control)

Yeah, should be all good. Ran it without any diff just now.
