Prior to this commit, I experienced the following use case:
Given I have the following code:
```emacs-lisp
(require 'rpgdm-dice "~/git/emacs-rpgdm/rpgdm-dice.el")
(require 'rpgdm-tables "~/git/emacs-rpgdm/rpgdm-tables.el")
(require 'rpgdm-tables-dice "~/git/emacs-rpgdm/rpgdm-tables-dice.el")
(require 'rpgdm-tables-freq "~/git/emacs-rpgdm/rpgdm-tables-freq.el")
(setq rpgdm-base "~/git/emacs-rpgdm/")
```
And I call `rpgdm-tables-load`
And load all the tables.
When I then call `rpgdm-tables-choose`
Then I get the following error:
```
let*: Symbol’s function definition is void: rpgdm-message
```
With this commit I'm able to skip requiring `rpgdm` and thus only use a
segment of the `rpgdm` package ecosystem.
