CommonJS or AMD dependencies can cause optimization bailouts

[agarciacalvo]

Building with Angular 10 throws this warning:

WARNING in C:...\node_modules\ng-gantt\fesm2015\ng-gantt.js depends on 'jsgantt-improved'. CommonJS or AMD dependencies can cause optimization bailouts.
For more info see: https://angular.io/guide/build#configuring-commonjs-dependencies

It's possible to have jsgantt-impoved built for ECMAScript?
