Transmuter V3 support with scaling factors.

[piobab]

The only reasonable way to determine version of the transmuter pool is through instantiate_msg schema in Pool response:

osmosisd query poolmanager pool 1212 --node https://rpc.osmosis.zone:443 --chain-id osmosis-1
pool:
  '@type': /osmosis.cosmwasmpool.v1beta1.CosmWasmPool
  code_id: "148"
  contract_address: osmo10c8y69yylnlwrhu32ralf08ekladhfknfqrjsy9yqc9ml8mlxpqq2sttzk
  instantiate_msg: eyJwb29sX2Fzc2V0X2Rlbm9tcyI6IFsiaWJjL0QxODkzMzVDNkU0QTY4QjUxM0MxMEFCMjI3QkYxQzFEMzhDNzQ2NzY2Mjc4QkEzRUVCNEZCMTQxMjRGMUQ4NTgiLCJpYmMvNDk4QTA3NTFDNzk4QTBEOUEzODlBQTM2OTExMjNEQURBNTdEQUE0RkUxNjVENUM3NTg5NDUwNUI4NzZCQTZFNCJdLCJhZG1pbiI6ICJvc21vMWdteDZ4OGxudmdobnl3YXpxY3l4NTZydDA3amRhdHJhY2hxZDRhZTA3M2doYXo3cmZ5bXFsZDd5NjAifQ==
  pool_id: "1212"

V1 (live on Osmosis mainnet):

{
  "pool_asset_denoms": [
    "ibc/072E5B3D6F278B3E6A9C51D7EAD1A737148609512C5EBE8CBCB5663264A0DDB7",
    "ibc/52C57FCA7D6854AA178E7A183DDBE4EF322B904B1D719FC485F6FFBC1F72A19E"
  ]
}

V2 (for now only available on Osmosis testnet):

{
  "pool_asset_denoms": [
    "uosmo",
    "factory/osmo14eq94mckd6kp0pwnxx33ycpk762z7rum29epr3/teko02"
  ],
  "admin": "osmo14eq94mckd6kp0pwnxx33ycpk762z7rum29epr3",
  "alloyed_asset_subdenom": "teko"
}

V3 (no live yet, contains normalization factors):
