feat: ability to specify a current employment

This commit allows the user to specify a company that they are currently
employed at.

Changes include:

- add present field to the Duration type.
- add durationToString function to output the duration type as a
formatted string.
- if the present field is used and the value is either 'true' or 'yes'
(case insensitive) this will be reflected on the CV.
- add durationToString to fmap.
- updated CV template to use the durationToString function.
