Stone Mason changes

I think that the stone mason villager is great, but I do have a few suggestions for changes to it. First off, why is the master level trade for a quartz pillar? This trade doesn't make much sense to me and I think you should be able to just buy quartz as the last trade and to remove the ability to sell quartz to the mason. Secondly, I think there should be a trade where you buy clay blocks because there is a lot you can do with clay if you don't make it into bricks and as it stands clay blocks are not renewable and only spawn in small amounts in bodies of water.
