[build]: Replace node_modules with a single-file bundle produced by…

… `ncc`

Detailed description of changes:

* Add `package` script to `package.json` that builds the TypeScript code
  and "links" it together with all of its (transitive) dependencies in a
  single `index.js` file.

* Change the `main` file in `package.json` to `dist/index.js`.
  `ncc` allows only the out dir can be specified - the filename is
  always `index.js`.

* Add `lib/` and `dist/*` to .gitingore, but exclude `dist/index.js` so
  it will be committed.

* Delete the `node_modules` and `lib` folders

* Add a `.gitattributes` file in order to set mark `dist/index.js` as
  `binary` for git diff and merge purposes

* Update `.gitignore` to the latest version from `https://github.com/github/gitignore/blob/master/Node.gitignore`

* Set the `target` in `tsconfig.json` to `es2017`, which is [supported by
  current Node.js version - v12][1], as should make for cleaner generated
  "down-leveled" code as it has native async/await support
