I've got a blank stress tensor, baby, and I'll write your strain

This makes a variety of updates to the strain module. The methods are demoed in and can be tested using two new notebooks in the tutorials repository, and which are also attached below. The basics_04 notebook is meant to be run after basics 01-03. Links to sample datasets are included in the markdown frontmatter of each notebook.

Great changes! I appreciate how swift-ly you updated this code and the new taylor-ed plotting functions.

I added to_strainmap method to BraggVectors, which is used as ~ strainmap = braggpeaks.to_strainmap(). Currently StrainMap is created strainmap = py4DSTEM.StrainMap(braggvectors=braggpeaks) which will still work. Feel free to revert if it you wish
