v1.0.9

Notes

I removed the binary PDF files, I'm trying to figure out how to automate the compilation and uploading of the PDFs using Github Actions.

This release provides you with the all.pdf file (below) that includes all the chapters, as a temporary fix until I figure things out.

What's Changed

• add proof for chapter 5.3 exercise 41 by @tenick in #15
