Returns a copy of this period with the amounts of each unit normalized.
!(p)
The process of normalization is specific to each calendar system.
For example, _in the ISO calendar system, the years and months are
normalized but the days are not, such that "15 months" would be
normalized to "1 year and 3 months".

This instance is immutable and unaffected by this method call.
