[Feature] Webpack v5 compatibility

• I’d be willing to implement this feature I tried to implement this feature but did not achieve completion; see #83

Describe the user story webpack v5.0.0 was released on 2020-10-10 and is likely to see gradual uptake as new projects begin using it and existing projects migrate to it. As a user of webpack v4 and mochapack, I’d appreciate the ability to have an upgrade path for my project in order to run tests based on webpack v5.

Describe the solution you’d like Upgrades to the mochapack CLI to support projects using webpack v5.

Describe the drawbacks of your solution webpack v5 introduces a number of breaking changes, and it’s unclear to me whether it would be possible to support both v4 and v5 from an updated mochapack codebase.

The support for Webpack 5 has been finished by @sodatea and included into mochapack@2.1.0, which has just been published.

@sodatea @jayaddison @skjnldsv Thank you so much for your work on the Webpack 5 support, it wasn’t possible without your time and efforts!

As a heads-up to anyone following this issue and keen to see it resolved; it’s being worked on in #83, but progress is slow since I don’t have much expertise in this codebase and - to be fairly honest about it - it is not yet a blocker or high-priority feature for the project I’m working on, so it tends to fall below other priorities.

Hopefully there’ll be a good reason to kickstart further progress soon; in the meantime if anyone’s getting a sense that their own work is unnecessarily delayed or blocked waiting for webpack v5 support in mochapack, your contributions and ideas for how to get this implemented are welcome.
