Include `graphql-lodash.bundle.js` in distribution.

[k00p]

This PR adds a build:dist script to package.json to include graphql-lodash.bundle.js in npm distribution, which gets copied from lib/ to a new directory dist/.

Sourcing the pre-built graphql-lodash.bundle.js is useful for scenarios where it is not feasible or desirable to build out a complete React application. For example, if you are integrating graphql-lodash in an express-graphql session, it is a fairly significant amount of work/code to set up the React stack and build out the GraphiQL interface, and then integrate graphql-lodash. It is relatively easy to build the graphql-lodash bundle, and include that as well as the GraphiQL bundle on a page as in the GraphiQL example.

The fetch function becomes:

      function grapQLLodashFetcher(graphQLParams) {
        const { query, transform } = window.GQLLodash.graphqlLodash(
          graphQLParams.query,
          graphQLParams.operationName
        );
        graphQLParams.query = query;
        return fetch('/graphql', {
          method: 'post',
          headers: {
            'Accept': 'application/json',
            'Content-Type': 'application/json',
          },
          body: JSON.stringify(graphQLParams),
          credentials: 'include',
        }).then(function (response) {
          if (response.ok) {
            return response.json();
          } else {
            return response.text().then(body => {
              throw Error(response.status + ' ' + response.statusText + '\n' + body);
            });
          }
        }).then(function (responseBody) {
          responseBody.data = transform(responseBody.data);
          return responseBody;
        });
      }

Using a dist/ directory is fairly common practice for providing bundles, but another route may be preferred.

By the way - this project is a really fun idea. Thank you!

An example of useful things that can be done when webpacks are included in repos.

In the lodash declaration the minimized JS is pulled from the lodash repo:

lodash = window.lodash = await require("lodash@4/lodash.min.js")

Any chance you would reconsider having the webpack available so that it could be used on "web REPL" apps like Observable or even in GraphiQL?
