Please provide peerDependency for webpack version

[btzdnl]

Currently, I can install the latest version (5.2.0) of awesome-typescript-loader in combination with Webpack 2.2.x with no warning whatsoever.

When running Webpack however, it all falls apart:

...\node_modules\awesome-typescript-loader\src\watch-mode.ts:5
                compiler.hooks.run.tapAsync('at-loader', function(params, callback) {
                 ^
TypeError: Cannot read property 'run' of undefined

    at Function.Module.runMain (module.js:693:10)
    at startup (bootstrap_node.js:191:16)
    at bootstrap_node.js:612:3

That’s because there’s no compiler.hooks in Webpack 2.x.

This problem could easily be prevented by specifying compatible Webpack versions in package.json.

Also having this issue, needed to update webpack to 4+.
