Here's a concise summary of the pull request changes:

Summary: This WIP pull request adds support for the NVIDIA Grace Hopper processor to the sensor feature in the devices package.

Key Modifications:

1. Introduced new types gpuGraceACPI and GraceACPI with device-specific functionality for the Grace Hopper.
2. Implemented methods for initializing and reading power data from the device.
3. Updated graceCheck and graceDeviceStartup functions to support the new type.
4. Added new functions findModulePowerPaths, readPowerFile, and AbsEnergyFromDevice to read power data from the Grace Hopper.

Impact: These changes affect the external interface and behavior of the code, enabling support for the NVIDIA Grace Hopper processor.

Observations/Suggestions:

• The changes seem to be well-structured and follow a consistent pattern.
• It would be beneficial to include unit tests to ensure the new functionality works as expected.
• Consider adding documentation or comments to explain the purpose and usage of the new types and functions.
• Review the code for any potential performance or security implications related to reading power data from the device.
