location requests should be remapped and exposed in SamplePose level

[Poofjunior]

Functions to implement that return values in sample pose space:

• get_lower_travel_limit
• get_upper_travel_limit
• get_position

~~More generally, there are inconsistent calls to remap axes. Some functions use _remap(...) while others just apply it directly from self.axis_mapping. We need to consolidate these.~~
