Fix exports

[stellarhoof]

• Add exports to package.json so node knows which version of the code to import
• Do not use esbuild to transpile source when running tests. Instead use jest ESM support
• Fix default exports when code is imported from CommonJS. Same solution as in https://github.com/smartprocure/contexture-client/pull/212
