Transaction builder in Typescript

[karczuRF]

Create Typescript Transaction Builder.
This should look sth like this:

new TransactionBuilder()
  .callMethod(account.withdraw, [XTR2, new BigNumber(10)])
  .putLastInstructionOutputOnWorkspace("fee")
  .callMethod(component.withdraw, [new Workspace(“fee”), new BigNumber(1)])
….
  .build();

In above, the methods like account.withdraw should be typed like something like TariComponentMethodDescriptor and

callMethod<T extends TariComponentMethodDescriptor>(method: T[“method”], argos: T[“args”])
