Checks if the specified unit is supported.
!(p)
This checks if the specified unit can be added to, or subtracted from, this year.
If false, then calling the {@link #plus(long, TemporalUnit)} and
{@link #minus(long, TemporalUnit) minus} methods will throw an exception.
!(p)
If the unit is a {@link ChronoUnit} then the query is implemented here.
The supported units are:
!(ul)
!(li){@code YEARS}
!(li){@code DECADES}
!(li){@code CENTURIES}
!(li){@code MILLENNIA}
!(li){@code ERAS}
</ul>
All other {@code ChronoUnit} instances will return false.
!(p)
If the unit is not a {@code ChronoUnit}, then the result of this method
is obtained by invoking {@code TemporalUnit.isSupportedBy(Temporal)}
passing {@code this} as the argument.
Whether the unit is supported is determined by the unit.
@param unit the unit to check, null returns false
@return true if the unit can be added/subtracted, false if not
