Redemptions that redeem close to 100% of the Trove Debt may revert when the hint is inaccurate

Impact

After a redemption, this comparison is performed:

https://github.com/blkswnStudio/ap/blob/8fab2b32b4f55efd92819bd1d0da9bed4b339e87/packages/contracts/contracts/RedemptionOperations.sol#L123-L129

      // resulting CR differs from the expected CR, we bail in that case, because all following iterations will consume too much gas by searching for a updated hints
      // allowing 1% deviation, because of time based borrowing interests
      if (troveRedemption.resultingCR > iteration.expectedCR) {
        if ((troveRedemption.resultingCR * DECIMAL_PRECISION) / iteration.expectedCR > 1.01e18) break; /// @audit Risk of overflow
      } else {
        if ((iteration.expectedCR * DECIMAL_PRECISION) / troveRedemption.resultingCR > 1.01e18) break;
      }

Whenever expectedCR or resultingCR are greater than type(uint256).max / 1e18 the multiplication will overflow, causing a revert

This may be used to grief other people, or can happen naturally due to slight changes in prices, or other redemptions

Mitigation

It may be best to use a smaller factor such as 100 as to reduce the likelyhood of an overflow
