calculatePresentValue cleanup

[jalextowle]

This PR cleans up the logic in calculatePresentValue and fixed a bug. This increased the codesize enough that the ERC4626HyperdriveDeployer exceeded the max code size of 24kb, so this PR also moves permitForAll into the HyperdriveTarget0 contract.

This is good. Just a few questions. Also, i think you need to update the names of the rust functions so the tests will pass.
