customfetch fails to differ between certain editions of cards

customfetch will fail to specialize between special editions of cards, for example, XT cards sold by AMD.

This is because they share the same device ID as their regular counterparts, but maybe there's an alternative way to get the device name?

For NVIDIA cards, the driver exposes the model name through /proc/driver/nvidia, Which we could probably find an equivalent for AMDGPU.
