Add pause library, make Mailbox pausable and with reentrancy guard #78

Closed tkporter closed 1 year ago

Adds pause library. Implemented it in a similar fashion to https://github.com/FuelLabs/sway-libs/tree/master/libs/ownership/src
Implements Pausable for the Mailbox contract, which lets the owner pause the contract
Makes dispatch revert if the contract is paused
Makes process revert if the contract is paused or there is reentrancy

interesting Think we're fine in this case though as none of the other contracts depend on stuff like whether a specific message has been delivered or not
