[SenorKarlos PR Port] Adding an option to hide the Pokemon stats

[darkelement1987]

Description

When encounters are activated, a malicious user can ask for all the statistics, even when the statistics are disabled by configuration in the JavaScript code.

With this change you can be able to hide the stats, so when the frontend asks for the Pokemon, it will return an array of Pokemon with all the statistics removed.

This doesn't affect at all to webhooks or database storage
