[Bugfix] Infinity Error

[rahul-tuli]

• Avoid division by zero
• Avoid log of zero

Test Script:

import numpy

def sparsezoo_analyze_infinity_error():
    from sparsezoo import analyze
    
    stub = "oberta-small-qqp_wikipedia_bookcorpus-base_quantized"
    analysis = analyze(stub)
    print(analysis)
    return analysis


if __name__ == "__main__":
    sparsezoo_analyze_infinity_error()

Output:
