Subject: [PATCH] Extract Hex class resource logic to a separate method (#20)

* feat: Extract Hex class resource logic to a separate method

Sorry for the weird commit message, I couldn't find a way to word it better. Anyways..

This commit extracts the `getResourceAsStream` call to a separate, protected method so it can be overrided, and we can provide the Hex class from a different source.

* fix: Check if Hex class stream is null
