Reduce bundle size with SWC

[tripodsgames]

Hello, I conducted some tests using SWC to reduce the file sizes and potentially improve the performance of this library.

Changes:

• Instead of publishing the "libs" folder, we now publish the "dist" folder.
• The TypeScript file is copied as soon as the build is finished, also to the "dist" folder.
• The examples and tests point to the "dist" folder and require the build to be done beforehand (npm run build).
• Currently, it is configured to export the maps (perhaps it's better to deactivate).

I would like to discuss the changes.
