PROTOTECH 49: Revert nicely if no `decimals()` method exists QT or CT

[ith-harvey]

Description of change

High level

• Created a hasDecimalsMethod() method which checks if a contract has a decimals() method
• Created a TokenInvalidNoDecimals revert if a contract doesn't have the decimals() method

Description of bug or vulnerability and solution

• Original Prototech issue: https://github.com/Fixed-Point-Solutions/prototech-ajna-audit/issues/49
• Although we point out that the decimals() method isn't required in the readme it wasn't reverting cleanly.
