FlashMintLeveraged: Support for fixed input Issuance (#169)

* Copy paste FlashMintLeveraged as starting point * Fix tests * Remove debug logs * Correct wrong eth logic, still failing because eth is sent back prematurely * Fix lint failure * Fix eth issuance by adjusting handling of input token, only paying back at the end * Fix fixedSetAmount issuance method and add related tests * Add redemExactSet tests back in * Adjust redemption methods * First version of exact output redemption * Add redemSetForExactETH method * Fix fixedOutputRedeem methods * copy paste ethereum integration test to new arbitrum integration test folder * Adjust arbitrum integration test addresses * Fix arbitrum integration test setup * More test fixes * Arbitrum tests green * Add arbitrum integration tests to ci * Set Arbitrum rpc url in env variables * update solidity-coverage * Remove ethereum integration tests for flashmintextended * Return excess eth in issueSetFromExactETH * Swap Input Token to ETH * Add swap data to ETH for redeem method * Temporarily comment out non-integration tests * Contract fixes * Fix test * More contract changes * Return amount of set token obtained from fixed input / output methods * Add maxIterations check * Add docstring comments and fix maxIterations check * more docstrings * Test issuance / redemption from / to usdc * Temporarily comment out polygon tests * Add maxGasRebate to protect against misconfiguration * Fix contract bug regarding eth rebate opt out * Extend tests * Re-Trigger CI * Use node 20 in github actions * Bump hardhat version * Update circleci node version * fix tests * fix tests * Deactivate optimism tests * only run optimistic auction rebalance tests in eth integration pipeline * fix tests * Inline doc comment * Remove test step from publish workflow * Fix tests
