Incorrect output for years 1 BC though 99 AD

[bucaneer]

The method getDateFromJulianDay passes the year value to the new Date() constructor, which has a documented legacy behavior with two-digit year values:

new Date() exhibits legacy undesirable, inconsistent behavior with two-digit year values; specifically, when a new Date() call is given a two-digit year value, that year value does not get treated as a literal year and used as-is but instead gets interpreted as a relative offset — in some cases as an offset from the year 1900, but in other cases, as an offset from the year 2000.

So dates dates that should have a year value from 0 through 99 (1 BC through 99 AD) are incorrectly rendered as 1900 through 1999.

Year value for the output Date object should instead be set using the setUTCFullYear() method.

Also, I think the package documentation should somehow make note of the date limits of the calculation. The Python package PyMeeus which appears to implement the same algorithm works for year values -1000 through 3000 (1001 BC through 3000 AD) and throws an exception otherwise.
