Add funds to contract execution

[iboss-ptk]

Is your feature request related to a problem? Please describe.
When contract execution requires funds, cosmy wasmy can't add funds to the execution.

Describe the solution you'd like
Take this contract for example, it sends stargate msg to osmosis' tokenfactory to create denom, and it requires creation fee.

It would be nice if we can add ##funds as an addition input for contract execution, parsed as coins and pass them to the execute function and strip them out before actually sending the msg. (could just extract and strip it here?)

{
  "create_denom": {
    "subdenom": "poopcoin",
    "initial_mint": "10000000000"
  },
  "##funds": [
    "1000000000uosmo"
  ]
}

Happy to contribute if you agree with the approach!

Yuupp. I been thinking on how to include option to send funds during msg call.
api.ts, as you linked, is a good place to handle that.

Would love your contribution :)
