Upload Stargaze Raffles v0.4.0

This proposal is to store the Stargaze version of the on-chain raffle contract, with AtlasDAO core team granted instantiate permissions.

The source code is available at: https://github.com/AtlasDA0/app-contracts

Features of the raffle contract include:
- Create & configure raffles permissionlessly
- Purchase raffle tickets
- Verifiable randomness to determine winner, via Nois Network
- Admin controlled params to optimize configuration
- Governance override contract lock via SudoMsg
- Static fee to creating raffles
- Raffle ticket sales tax

### Compile Instructions
sh<br />docker run --rm -v \$(pwd)\:/code \\<br /> --mount type=volume,source=\$(basename \$(pwd)\)_cache\,target=/target \\<br /> --mount type=volume,source=registry_cache,target=/usr/local/cargo/registry \\<br /> cosmwasm/optimizer:0.15.0<br />
determine the checksum
sh<br />sha256sum artifacts/raffles.wasm<br />
This results in the following SHA256 checksum:
<br />d7656019911745b97b54db86f6df2ef0a59ceaa12f70f358dd98fb8e29361720 raffles.wasm<br />
