/**
* @notice Calculates the net profit in KP3R a keeper would get for working a job registered in Keep3rV2.
*
* @dev This function should only be used for mainnet jobs that pay in KP3R or bonded KP3R. The main use of this
* function is to use it after a simulation and before sending the bundles to gauge whether working would be
* profitable or not with that priority fee.
*
* @param txHash Hash of the transaction in which the keeper worked the job.
* @param keep3rHelper Instance of the keep3rHelper contract.
* @param provider The provider to use to make a call to the keep3rHelper contract.
*
* @return The net profit for working a job denominated in KP3R.
