These (5-8) use the default 0.075 ohm sense resistor.

This PR adds a lookup table for known stepsticks (more will be added as time goes on), some logic for a new config option called 'stepstick_type', and documentation on the logic.
Heres the rundown:
If sense_resistor is defined: use it with full priority, no exceptions
else if stepstick_type is defined: use its lookup table value for sense_resistor
else use tmc default and warn user
if stepstick_type is defined: use its max_current value
else use tmc default
While I agree we should not have defaults set for configuration options like this, I also am not a fan of breaking everyones configs at this state in the project.
