Configuration YAML system - change to relative path
## Overview
The YAML config file (sensor) has an option to say where the data is found. This supports relative paths, however the relative path is from the kernel running the code. Change this so the relative path is given from wherever the YAML config is located.
## Motivation
More intuitive when using relative paths, configs and data can be kept together.
## Technical Requirements
## Dependencies/Interactions
YAML
## Acceptance Criteria
- [ ] When importing data with relative paths in YAML the relative path is relative to the YAML config location.
## Notes and Future Considerations
