Calendar months, period grains and origin periods.
Shared by every crate that keys results by period: prospicio-reserving
(triangle origins) and prospicio-prob (predictive-distribution components),
so a reserve component joins back to its triangle origin directly.
Moved here unchanged from prospicio-reserving (PR #9), apart from the
error type.
Development ages are whole months measured from the start of the origin period, so a triangle only ever needs month resolution: an age of 12 months on an origin starting January 2021 is valued at the end of December 2021.
