Dependency on @babel/runtime in esm versions

[vitalymind]

hi, I am trying to use three-nebula as es module. I assume that after installing npm package "..\node_modules\three-nebula\build\esm" folder should contain pre-built and ready to use library.

However I found following imports that likely should not be there, namely:

7 times import _defineProperty from "@babel/runtime/helpers/defineProperty"; in files:
\three-nebula\build\esm\core\fromJSONAsync.js
\three-nebula\build\esm\initializer\BodySprite.js
\three-nebula\build\esm\initializer\constants.js
\three-nebula\build\esm\initializer\Texture.js
\three-nebula\build\esm\renderer\GPURenderer\Desktop\index.js
\three-nebula\build\esm\renderer\GPURenderer\Mobile\index.js
\three-nebula\build\esm\utils\index.js

1 time import _objectWithoutProperties from "@babel/runtime/helpers/objectWithoutProperties"; in file
\three-nebula\build\esm\initializer\Position.js

From what I understand built three-nebula should not depend on babel, babel used only for building three-nebula it self.
Just to make it clear, minified built version "three-nebula.js" works as expected, no dependency on babel

Can it be fixed?
