[enhancement] more printout

[gsavva]

Adding more printout.

• UUID for AMD GPUs
• more info for occupation matrices: atom label and spin channel
• Calculate and print the eigenvalues of the occupation matrices

QE prints the eigenvalues of the occupation matrices by default (which would be very useful for quick comparison)

[gsavva]

The eigenvalues and the occupation matrices are printed with the following format:
