PalLoanToken

PalLoanTokens are ERC721 tokens to represent the ownership of a PalLoan. Each token has an id, is linked to a PalLoan (by the address), and to a Borrow in the PalPool that created the PalLoan.
PalPools only can mint and burn PalLoanToken.
When a PalLoanToken is burned, a burnedPalLoanToken is minted with the same token Id, representing closed (or killed) Borrows/PalLoans.
PalLoanTokens represent active PalLoans and burnedPalLoanTokens represent closed PalLoans.
