Beta version 1 released

This new beta release comes with a lot of new changes to the API that were mostly implemented in #412. This was done in conjunction with @atorchylo and helpful comments from @aguinot. The pipeline infrastructure changed to be more transparent and more modular. Summary of changes included below:

• Major improvements to user interface and codebase readability.
• New classes to organize and standardize blend information and output of deblenders. (BlendBatch + DeblendBatch)
• Increased modularity: it’s now easier to single out and use a particular functionality within BTK.
• New matching module to customize matching between truth and predicted catalog.
• New measure module that allows users to easily access relevant quantities of interest for blending studies: ellipticities, aperture photometry, SNR, blendedness.
• Improved metrics module with a variety of individually implemented metrics ⇒ easier to access and for new developers to add new metrics.
• New deblend module that incorporates deblenders into the BTK framework so far we have: Scarlet/PeakFinding/SEP
