feat: add getStarkProfiles function & tests

[irisdv]

Close #30

This PR :

• moves some utils functions into a new internal file
• adds a try catch for all calls that included a call to address_to_domain. We will first try to make the call with a hint parameter, if it fails we will make the call without the hint parameter.
• Blobbert tokenURI function was taking too much resources and resulted in the function getStarkProfiles returning an error whenever there was more than one profile with a Blobbert. For now, we don't retrieve those. We contacted the team and we will find a way (maybe offchain) to serve the token uri of users that have set a Blobbert as there pfp.
