Print messages when designer arguments are overridden

[clarabicalho]

For example in two_arm_designer(), when both ate and treatment_mean are provided and don't match, return warning message of the sort "Arguments treatment_mean and ate are both provided. The design uses the value of treatment_mean."

[jaspercooper]

Yes, absolutely agree with this. Any sense of where this is occurring?

This would apply to:

• binary_iv arguments a, b, d, a_Y, b_Y, d_Y
• block_cluster_two_arm, two_arm_covariate, two_arm arguments ate and treatment_mean
• two_by_two arguments mean_... and outcome_means

And some N arguments and some SD arguments I think ?

Good point, this also applies to factorial argument sd and outcomes_sd.

I think the existing checks/messages in block_cluster_two_arm handle well the more complex cases of N and sd.
