Develop new UniswapRouter-like contract

[hieronx]

Permissionless claiming
Why: removes 1 transaction required for Prime users

Lock tokens before added as member
Why: allows Prime users to submit the investment transaction before they have fully finished the legal onboarding steps

Multicall support
Add https://github.com/Uniswap/v4-periphery/blob/main/contracts/base/Multicall.sol to Router.

Why: claiming investment and submitting investment or redemption should be possible in 1 tx

contract LiquidityPoolRouter is Multicall {
 
  // --- Interactions ---
  function requestDeposit(address liquidityPool, uint256 assets) external {
    asset.transferFrom(msg.sender, address(this), assets);
    liquidityPool.requestDeposit(...);
  }

  function claimDeposit(address liquidityPool, address investor) external {
    // TODO: claim deposit, send tranche tokens to investor
  }

  function requestRedeem(address liquidityPool, uint256 shares) external {
    share.transferFrom(msg.sender, address(this), shares);
    liquidityPool.requestRedeem(...);
  }

  function claimRedeem(address liquidityPool, address investor) external {
    // TODO: claim deposit, send currency to investor
  }

  // --- Lock before member ---
  mapping (address investor => mapping (address liquidityPool => uint256 amount)) lockedRequests;

  function lockRequestDeposit(address liquidityPool, uint256 assets) external {
    asset.transferFrom(msg.sender, address(this), assets);
    lockedRequests[msg.sender][liquidityPool] += assets;
  }

  function executeLockedRequestDeposit(address liquidityPool, address investor) external {
    liquidityPool.requestDeposit(assets, address(this), investor, "");
    lockedRequests[msg.sender][liquidityPool] -= assets;
  }

  // --- View methods ---
  function getLiquidityPool(uint64 poolId, bytes16 trancheId, address currency) external view returns (address) {
    // TODO
  }
