Add ability to lazy load each component individually

[axelthat]

Is your feature request related to a problem? Please describe. File Uploader is a huge component for someone that only wants to use the minimal uploader with minimal functionalities. Thus, being able to lazy load each component individually would boost the initial page load performance by a lot.

Describe the solution you'd like Add ability to lazy load each component individually

Describe alternatives you've considered No alternatives but would love to do something like this:

    import('@uploadcare/file-uploader/blocks/BaseComponent/BaseComponent'),
