Obtains a {@code Duration} representing an amount _in the specified unit.
!(p)
The parameters represent the two parts of a phrase like '6 Hours'. For example:
!(pre)
Duration.of(3, SECONDS);
Duration.of(465, HOURS);
</pre>
Only a subset of units are accepted by this method.
The unit must either have an {@linkplain TemporalUnit#isDurationEstimated() exact duration} or
be {@link ChronoUnit#DAYS} which is treated as 24 hours. Other units throw an exception.
@param amount the amount of the duration, measured _in terms of the unit, positive or negative
@param unit the unit that the duration is measured _in, must have an exact duration, not null
@return a {@code Duration}, not null
@throws DateTimeException if the period unit has an estimated duration
@throws ArithmeticException if a numeric overflow occurs
