### Example

```
strategiesByPairl(
 0x514910771AF9Ca656af840dff83E8264EcF986CA, //token0
 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, //token1
 0, //startIndex
 25, //endIndex
)

// returns
// [(Strategy), (Strategy), (Strategy)]

// struct Strategy {
//    uint256 id;
//    address owner;
//    Token[2] tokens;
//    Order[2] orders;
// }

// Order objects:
//        [
//            Order({
//                y: uint128,
//                z: uint128,
//                A: uint64,
//                B: uint64
//            }),
//            Order({
