Vulnerability details

The following require messages are of length more than 32 and we think are short enough to short
them into exactly 32 characters such that it will be placed in one slot of memory and the require
function will cost less gas.
The list:

    Solidity file: SushiswapStrategy.sol, In line 53, Require message length to shorten: 38
    Solidity file: SushiswapStrategy.sol, In line 74, Require message length to shorten: 33
    Solidity file: UniswapV2Strategy.sol, In line 53, Require message length to shorten: 38
    Solidity file: UniswapV2Strategy.sol, In line 74, Require message length to shorten: 33
    Solidity file: MapleProxyFactory.sol, In line 33, Require message length to shorten: 36
    Solidity file: MapleProxyFactory.sol, In line 42, Require message length to shorten: 36

Agreed with 4 out ot 6, but these aren't bugs.

SushiswapStrategy.sol, line 53: agreed, it would be better as "SS:WRONG_COLLATERAL_AMT" or "SS:WRONG_COLLATERAL"
SushiswapStrategy.sol, line 74: agreed, it would be better as "SS:TRANSFER_FAILED"
UniswapV2Strategy.sol, line 53: agreed, it would be better as "U2S:WRONG_COLLATERAL_AMT" or "U2S:WRONG_COLLATERAL"
UniswapV2Strategy.sol, line 74: agreed, it would be better as "U2S:TRANSFER_FAILED"
MapleProxyFactory.sol, line 33: possibly it can be "MPF:DUP:NO_OVERWRITE_INITIALIZER" but it would be grammatically awkward
MapleProxyFactory.sol, line 42: possibly it can be "MPF:EUP:NO_OVERWRITE_INITIALIZER" but it would be grammatically awkward

Valid optimization.
