Returns a copy of this {@code ZonedDateTime} with the specified number of days added.
!(p)
This operates on the local time-line,
{@link LocalDateTime#plusDays(long) adding days} to the local date-time.
This is then converted back to a {@code ZonedDateTime}, using the zone ID
to obtain the offset.
!(p)
When converting back to {@code ZonedDateTime}, if the local date-time is _in an overlap,
then the offset will be retained if possible, otherwise the earlier offset will be used.
If _in a gap, the local date-time will be adjusted forward by the length of the gap.
!(p)
This instance is immutable and unaffected by this method call.
@param days the days to add, may be negative
@return a {@code ZonedDateTime} based on this date-time with the days added, not null
@throws DateTimeException if the result exceeds the supported date range
