Sliding window changes

[mibur1]

Hi @mtorabi59

I implemented the changes as discussed in #31.

The changes are:

• Removed extending the window which has two effects:
  • Bugfix regarding the zero-padding for rectangular SW calculation
  • Limits the tapered window to contain no samples outside the window width
• Added a window_std parameter to Sliding Window, Discrete HMM, and Sliding Window Clustering
  • Default is None, which results to the original std of 3 * W / 22
• Disabled the convolution and instead directly use the Gaussian
  • In my opinion this is unnecessary now, as the window size is a hard limit for the window
• Vectorized Pearson correlation calculation for improved performance

Feel free to modify this to your liking. Also I did not write any tests/documentation, please let me know if I should do so :)

Thanks @mibur1 ! Overall it looks good! Thank you for making the changes. There a few comments below:

@mibur1 lmk if you have any Qs!
Also, tests are not necessary, but if you have some ideas for testing the sliding window, it'd be great to have them!

@mtorabi59 Thanks for the quick review and comments, I hope I addressed all of them. I will think about tests for the sliding window and add some if I have an idea.

@mibur1 Thanks, everything looks good! There might only be some formatting changes by black or flake8.

@mibur1 If you're familiar with pre-commit, it would be great to run it locally and make the required formatting changes, ow I'll fix them!

Thanks! I'll try to do this as well as the unit tests next week. But please feel free to do it yourself if you would like to have it done earlier.
