feat(lib): new bot abstraction library

following the idea from [Comicverse's library
package](https://forge.capytal.company/capytalcode/project-comicverse/src/branch/main/lib),
a new package inside the "lib" folder was created, to make a abstraction
over the discordgo package. The idea is to follow something similar to
the http package with it's router with Handle functions and with
inspirations from the package
[Disgolf](https://github.com/FedorLap2006/disgolf).
