refactor: add structure for start and end dates

The start and end dates for employment and
education experiences were free-form strings.

This commit changes adds a Date struct with Year and Month
variables and declares the Duration field as a type Date.

The TEX template is updated to reflect the change. The resulting
PDF will not change.
