Upload Transmuter v3.1

Transmuter is a CosmWasm contract that allows 1:1 conversion of one asset to another by establishing a new CosmWasm pool type. \n\nThis release is based on feedback from initial usage and includes two main updates: \n* Allow alloys to start with single asset\n * This allows alloys to be created where there is only a single asset at the moment without having to do a liquidity migration as more bridges become available. \n* Increased restrictions on subdenom validation at creation. \n * This allows the subdenoms to be parsed more easily since they have predictable formatting. \n\nRelease: https://github.com/osmosis-labs/transmuter/releases/tag/v3.1.0 \n\nForum Thread: https://forum.osmosis.zone/t/upload-transmuter-v3-as-cw-pool/2720/4
