- Exercise: MoreCoolStuff-1
Write a sigil ~v that parses multiple lines of comma-separated data, returning a list where each element is a row of data and each row is a list of values. Don’t worry about quoting—just assume each field is separated by a comma.
csv = ~v""" 1,2,3 cat,dog """would generate [["1","2","3"], ["cat","dog"]].

The function Float.parse converts leading characters of a string to a float, returning either a tuple containing the value and the rest of the string, or the atom :error.
Update your CSV sigil so that numbers are automatically converted.
csv = ~v""" 1,2,3.14 cat,dog """should generate [[1.0,2.0,3.14], ["cat","dog"]].
