Add a FIFO/LIFO IRedeemOptimizer realisation.

[jplodge-pro]

Abstract

As discussed with @lucasia thus:

hi Jonathan - thinking about it now, FIFO for deposits with 10% and LIFO for the others.

• seller wants the 10% yield first - FIFO here
• if they don't have enough of the 10% yield to cover, they probably want what's been held the "least" amount of time. so the other holdings can earn 10% faster.

To Do

• Add a IRedeemOptimizer that encapsulates the above strategy.
• Add a RedeemOptimizer base realisation to encapsulate common behaviours.
• Ensure the optimizer is robustly tested with full coverage.
• Tweak the IMultiTokenVault to include the ERC1155Supply exists(uint256 id), because:
  • This will allow any IRedeemOptimizer to seamlessly track the first period that has any deposits against it. This is the typical starting point of optimisation.
