refactor(CircuitJs): TS generator to not emit function wrapper if noir function name is a TS keyword

[rahul-kothari]

Say I write a noir function throw().
I compile my contract and generate a typescript interface.....and the interface blows up because throw() is a TS keyword!

Solution could be

• TS generator will not emit any function named after a TS keyword, and emits something to the effect of WARNING: Function 'throw' not emitted as conflicts with keyword. Can be called via function index e.g.: contract["throw"]() You can call this method manually.
