PySODMetrics: A simple and efficient implementation of SOD metrics

Introduction
A simple and efficient implementation of SOD metrics.

Based on numpy and scipy
Verification based on Fan's matlab code https://github.com/DengPingFan/CODToolbox
The code structure is simple and easy to extend
The code is lightweight and fast

Your improvements and suggestions are welcome.

Reference

Matlab Code by DengPingFan(https://github.com/DengPingFan): In our comparison (the test code can be seen under the test folder), the result is consistent with the code.

The matlab code needs to change Bi_sal(sal>threshold)=1; to Bi_sal(sal>=threshold)=1; in https://github.com/DengPingFan/CODToolbox/blob/910358910c7824a4237b0ea689ac9d19d1958d11/Onekey_Evaluation_Code/OnekeyEvaluationCode/main.m#L102. For related discussion, please see the issue.
2021-12-20 (version 1.3.0): Due to the difference between numpy and matlab, in version 1.2.x, there are very slight differences on some metrics between the results of the matlab code and ours. The recent PR alleviated this problem. However, there are still very small differences on E-measure. The results in most papers are rounded off to three or four significant figures, so, there is no obvious difference between the new version and the version 1.2.x for them.
