Summary: Load recommended modules on demand when available

Description:
This module gathers a list of recommended modules and versions and
provides means to check if they are available. It is a thin veneer
around Module::Runtime.

There are two major benefits over using Module::Runtime directly:

* Self-documents recommended modules together with versions at the top
of your code, while still loading them on demand elsewhere.

* Dies if a recommended module exists but fails to compile, but
doesn't die if the module is missing or the version is insufficient.
This is not something that Module::Runtime offers in a single
subroutine.
