templatize tool change scripts

[Poofjunior]

Currently, we need to manually bookkeep offsets across multiple Duet macros. This is cumbersome and prone to error once the machine is deployed into a production environment (i.e: the lab).

Alll boilerplate macros should be defined automatically from a set of high-level variables. These variables include:

• the tool's XYZ offset
• any travel region limitations based on the tool's size
• any speed limitations for this tool
