Add support for --inspect and --inspect-brk options

[papinto]

Mocha supports the --inspect and --inspect-brk options:
--inspect // activate devtools in chrome
--inspect-brk // activate devtools in chrome and break on the first line

It would be helpful if mochapack can pass these options through to mocha.

@papinto Yep, agreed. Good point!

This is critical for our development flow, as it enables debugging any issues in the runtime.

Are there any plans to add this soon?

I guess you are looking to get good debugging experience with this tool, not just pass --inspect to node. The latter is easy, just launch it as node node_module/.bin/mochapack --inspect --inspect-brk ....

The former, i.e. getting good debugging experience is more tricky. The debugging support is there for quite a while and it is documented:
https://sysgears.github.io/mochapack/docs/guides/ide-integration.html

I have submitted example project that follows the docs to set up debugging, in this PR:
#10

It mostly works for me, but there is rather nasty issue, that on the first mochapack run my breakpoints do not get hit, on the second run they work fine. So in order to debug I have to start mochapack in watch mode, then allow it to run the tests, then I set breakpoint in the test of concern and modify this test slightly, this triggers second run of mochapack and my breakpoint hit this time (teseted in VS Code and in Google Chrome)
