delays webpack aggregateTimeout triggered watch-build until some custom condition meets

[!WARNING]
It's fine if you use this library from NPM package with a static versioning in case you want it for some pet-project or to test it's capabilities.

But for production use it's strongly recommended to create a fork, because I do not write Changelogs and may break / add some functionality without notice.

Fork of conditional-aggregate-webpack-plugin with support of aggregated changes.
