Write a C# program that calculates an estimate of the carbon footprint (in kg of CO2) for an automated delivery rover traveling a distance between 2 and 25 kilometres.

Your program should:

• Keep asking the user to enter a travel distance in kilometres until they enter a value that is between 2 and 25 (inclusive).
• Calculate the base carbon footprint by multiplying the entered distance by 0.35.
• Ask the user if 'heavy payload' mode is enabled (expect the user to enter yes if it is).
• If heavy payload mode is enabled, multiply the calculated carbon footprint by 1.6.
• Output the final calculated carbon footprint in kg.

You should use meaningful variable names, correct syntax, and appropriate indentation in your answer.
