PoC Optimism TX auction

[poszu]

This pull request introduces a new example project, optimism-tx-auction, which includes Solidity contracts, Rust client code, and supporting configurations. The changes add functionality for submitting bids to an auction and retrieving bid data using a Rust client. Key additions include the Solidity contract, Rust bindings and client, and a script for submitting transactions.

New Example Project: optimism-tx-auction

Submodule and Project Setup:

• .gitmodules: Added a new submodule for forge-std under the optimism-tx-auction project.
• Cargo.toml: Included examples/optimism-tx-auction in the list of project members.
• examples/optimism-tx-auction/Cargo.toml: Defined the Rust package for optimism-tx-auction with dependencies such as pod-sdk, alloy, and tokio.

Solidity Contract:

• examples/optimism-tx-auction/contract/src/Auction.sol: Added a Solidity contract for the auction, including a submitBid function and an event BidSubmitted.

Rust Client for Auction:

• examples/optimism-tx-auction/src/client.rs: Implemented an AuctionClient in Rust for interacting with the auction contract, including a method to retrieve bids (bids) based on a deadline.
• examples/optimism-tx-auction/src/bindings.rs: Added Rust bindings for the Solidity contract using the alloy::sol! macro.
• examples/optimism-tx-auction/src/lib.rs: Defined modules for bindings and client functionality.

Supporting Files and Scripts:

• examples/optimism-tx-auction/contract/.gitignore: Added .gitignore rules for development and build artifacts in the Solidity contract directory.
• examples/optimism-tx-auction/contract/foundry.toml: Configured Foundry settings for Solidity compilation and development.
• examples/optimism-tx-auction/submit_txs.sh: Added a Bash script for submitting transactions to the auction using predefined private keys.
