* This commit adds error checking to prevent desklet or Cinnamon crashes
when any of the used files are absent from the system, most often
because the system doesn't have a gpu from AMD.
It also switches amdgpu functions to use async function calls for
file reading, like the rest of the desklet.

* This commit adds support for showing GPU and VRAM usage on GPUs
which make use of the amdgpu driver.
It should be noted that GPU usage can be somewhat inaccurate
because of the low sampling frequency.
