# Slot index of the output proposal within the output proposal list is calculated as follows:
# OUTPUT_PROPOSAL_SLOT_INDEX = keccak( bytes32( SLOT_INDEX ) ) + ( OUTPUT_PROPOSAL_INDEX * OUTPUT_PROPOSAL_SIZE)
#
# - SLOT_INDEX is 0x3
# - OUTPUT_PROPOSAL_INDEX is the element index within the list of proposals. Something the user needs to provide
# - OUTPUT_PROPOSAL_SIZE is the size of the OutputProposal struct in bytes32 words. Looking at the smart contract that
#   defines (https://github.com/polymerdao/optimism/blob/develop/packages/contracts-bedrock/src/libraries/Types.sol#L13)
#   we can see this is 2 bytes32 words
#
# Putting it together we have:
#
# OUTPUT_PROPOSAL_SLOT_INDEX = \
# 	keccak( 0x0000000000000000000000000000000000000000000000000000000000000003 ) + \
