Given a list of years and a reference year, return a list where the years are ordered by their distance from the reference year, with the closest years appearing first.

Write a function sort_years_by_distance(years, reference_year) that takes a list of years and a reference year as arguments. The function should compute the absolute distance of each year from the reference year and return a new list sorted by these distances.

Example

If the input is:

years = [1990, 1985, 2000, 1995]
reference_year = 1993

The expected output would be:

[1995, 1990, 2000, 1985]

This is because 1995 is 2 years away from 1993, 1990 is 3 years away, 2000 is 7 years away, and 1985 is 8 years away.
