Add visual examples to README example section

[ChiefOfGxBxL]

The example section of the README.md shows a code snippet that doesn't offer much insight because it skips over both the JSON and WC3 "native" data.

Use a specific translator for the code snippet, and then show two side-by-side images:

1. WC3 hex code
2. JSON format

so developers can see the data in two formats, and how JSON is easier to read and work with.
