Run-time errors after release of v2.4.1

[thinkh]

LineUp breaks in our apps after the release 2.4.1 with the following run-time error:

Uncaught (in promise) TypeError: Class constructor ACellTableSection cannot be invoked without 'new'
    at new EngineRanking (EngineRanking.js:71:1)
    at MultiTableRowRenderer.<anonymous> (EngineRenderer.js:277:1)
    at MultiTableRowRenderer.pushTable (MultiTableRowRenderer.js:107:1)
    at EngineRenderer.push.6NJj.EngineRenderer.addRanking (EngineRenderer.js:276:1)
    at Object.<anonymous> (EngineRenderer.js:225:1)
    at Dispatch.apply (dispatch.js:61:59)

    at LocalDataProvider.push.gwz5.AEventDispatcher.fire (AEventDispatcher.js:84:1)

I think the error is caused by the updated tsconfig.json. We should revert/downgrade version and match the one in lineupjs.

lineupengine/tsconfig.json
