Roman Numerals for GameMaker

ever wanted to be able to format numbers in Roman numerals/parse Roman numerals in GameMaker? probably not, but because i was already a disappointment to my ancestors and i see no reason to break the tradition, i made a thing that can do exactly that for you

from_roman_numeral(str) will parse a roman numeral (case insensitive):

from_roman_numeral("CccLxvi") -> 366

to_roman_numeral(number) will format a number as a roman numeral; the number must be positive and will ignore decimals

to_roman_numeral(1234) -> "MCCXXXIV"

values over 3000ish will just append Ms because you honestly shouldn't ever really need a number bigger than 3000ish for anything anyway (source: the romans, apparently)

string_roman_numerals_only(str) will return a string containing only valid roman numeral characters (case insensitive), sort of like string_digits() for number systems that suck
