feat: add workday endpoint

Added support for our latest endpoint, which calculates the workday a
given number of business days into the future from the given date for
the given country.

Also:
* perf: updated dependencies
* ci: pinned eslint to 7.2.x due to airbnb incompatibility with 7.3.x.
* ci: tweaked / improved eslint rules a bit.
* refactor: updated types to use `;` and include weekday response.
* docs: added example for new endpoint.
