After updating the `tbtc-v2.ts` lib with new version for `goerli`, we've
ecnoutered a problem running dApp:
```
Failed to compile.
./node_modules/ecpair/src/ecpair.js 82:7
Module parse failed: Unexpected token (82:7)
File was processed with these loaders:
* ./node_modules/react-scripts/node_modules/babel-loader/lib/index.js
You may need an additional loader to handle the result of these loaders.

As you an see it is related to the `ecpair` lib that we've installed in
`tbtc-v2.ts` and it has something to do with our `webpack`. As a solution I've
installed a babel plugin - `@babel/plugin-transform-class-properties` - and
added it to the craco config with the `loose` option.
You can see more information about this plugin in the babel docs:
https://babeljs.io/docs/babel-plugin-transform-class-properties.
