fix!: export package as bundled ESM

[ph-fritsche]

What:

Export package as bundled ESM

Why:

Closes #813
Closes #757

How:

The package is supposed to be consumed per default export.

Switch to an ESM export because CJS has no default export.

Bundle package because the semantically correct import paths in TS might not translate to universally correct import paths in ESM.
