Unified GLM algorithm

[oooo26]

• Add _abessGLM in AlgorithmGLM.h as the base GLM class
• Rewrite Logistic/Poisson/Gamma Regression on the basis of _abessGLM, which would be much simpler
• Fix zero-weight sample bug #458

• Fix zero-weight sample bug Samples with zero weight can affect the result. #458

It would be better if you could document the changes in the change log https://abess.readthedocs.io/en/latest/Changelog.html after it is merged.

Sure, I will update both the change log and development guide later.
