old_storage new_storage lazy_storage_diff returns a map from ticket-tokens to balance-differences that represents the change in balance for a contract due to changes of tickets in the storage. The assumption is that before calling ticket_diffs, all tickets that are owned by a contract exist either in the old_storage or the arg. After execution, only tickets in new_storage are owned by the contract. Note that this function avoids traversing the lazy part of the storage.

Mavryk_protocol_environment_001_PtAtLas.Lwt.tupdate_ticket_balances ctxt ~self_contract ~ticket_diffs operations updates the ticket balances according to the ticket_diffs map and the set of operations. The function also returns the storage size diff resulting from updating the ticket-balance table in the context.
Invariant: this function must be called after applying the lazy-storage diffs affecting any contracts in the given operations.
The function fails in case an invalid ticket-token-balance update is detected. The ticket_diffs argument represents the change of ticket-tokens for the self contract. It also specifies a "budget" for outgoing ticket-tokens.
