Feature/add hashmasks

[Tibike6]

1. I have fixed the problems and the typo from KnownOrigin.
2. I have added Hashmasks to the subgraph
   One problem is that they do not implement IERC721Metadata (no tokenURI), so that the data is not in the blockchain. But they are available on the website. Since there are only 16384 in total I use the static ipfs links from there. What do you think?

Thank you @Tibike6!
I've moved the fix for the KnownOrigin to a separate branch #16 for the sake of clarity

[frostiq]

I'll resolve the merge conflicts that occurred after the separation

[frostiq]

@Tibike6, yeah this should work, as there is no other option
Can I ask you to move this array to a separate hashmask-ipfs-uri.json file and just import it in the mappings?

[frostiq]

Also I didn’t get the relation between token ID and IPFS URI, could you please tell me more about how you created this array of URIs?
I've looked at hashmask list and it seems that the order is different there, but I guess that index is not the same as token id, right?

The data is a bit hidden. Main page => Record and Proof => https://www.thehashmasks.com/provenance.html

I will try it. I hope it works in AssemblyScript
