modernise dist folder & bundle adaptors with treeshaking

[mesqueeb]

I was confused about how to import adaptors until I saw this thread:
#568

I am under the impression that we could improve the way to import adaptors to support a syntax similar to:

import { indexedAdapter } from 'lokijs'

When we provide separate package.json entry points with eg. main and module fields, we could use something like Rollup to easily provide a CommonJS distribution script for main which will work in NodeJS environments and provide the ESM (ES module) distribution script for module for browsers and bundlers like Webpack and Rollup.

Bundlers would treeshake the main lib to only take out the adaptor in case the import method like above is used.
