What is the Problem Being Solved?

FastUSDC has various components that require offers - LPs, oracle operators. To facilitate client build out and integration testing, we should export an Offers object a la inter-protocol/src/clientSupport.js: https://github.com/Agoric/agoric-sdk/blob/master/packages/inter-protocol/src/clientSupport.js#L429-L455

Description of the Design

• export Offers object with offer makers, like https://github.com/Agoric/agoric-sdk/blob/master/packages/inter-protocol/src/clientSupport.js#L429-L455
• export helpful types and constants, like CctpEvidence and TxStatus
• use them somewhere, like multichain-testing/test/fast-usdc/fast-usdc.test.ts and/or packages/fast-usdc/src/cli/cli.js
