[FEATURE]: Replace "platform" with workbench or table

[evan-palmer]

Feature Type

Changing existing functionality in the Alpha driver

Problem Description

The platform is a fine way to integrate initial support for gazebo. Though, other projects typically use an object like a table or workbench instead of a simple cube geometry.

Feature Description

Replace the "platform" with a table or workbench model. This will make things a bit more visually appealing, especially for new users.

Alternative Solutions

I would ultimately prefer to not have a platform at all, but I think a table is a nice solution too.
