feat: Add Typechain

[fzavalia]

Add typed contracts created with typechain when published.

Current issues:

When imported in the builder and used, everything works when started with npm start. However, when running the tests, there is an error regarding this library that is:

 FAIL  src/modules/ens/sagas.spec.ts
  ● Test suite failed to run

    Jest encountered an unexpected token

    This usually means that you are trying to import a file which Jest cannot parse, e.g. it's not plain JavaScript.

    By default, if Jest sees a Babel config, it will use that to transform your files, ignoring "node_modules".

    Here's what you can do:
     • If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/en/ecmascript-modules for how to enable it.
     • To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
     • If you need a custom transformation specify a "transform" option in your config.
     • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.

    You'll find more details and examples of these config options in the docs:
    https://jestjs.io/docs/en/configuration.html

To try it for yourself, you can checkout decentraland/builder#2615 and run the tests.

If you want to compile this lib locally and import it in the builder to try changes, I recommend:

# decentraland-transactions
npm ci --legacy-peer-deps
make build
cd dist
npm pack

# builder
npm i /decentraland-transactions/dist/decentraland-transactions-0.0.0-development.tgz
npm test

Now that we have changed the build process, we can modify the jest configuration to transform the typechain module into a ES6 module.
