Roman Numerals

Create a function that takes in a Roman numeral as a string and converts it to an integer, returning the result. The function should work for all Roman numerals representing positive integers less than 4000

Notes

• All letters will be in uppercase.

• Assume all inputs will be well-formed Roman numerals.

• While you could probably solve this by separately checking for each of these

  sequences inside the string, there is a smarter way. Think about the numerical value each individual letter has, and how the letter immediately following it can affect that letter's numerical value.
