cannot use macro `\newcommand` about mdbook-katex HOT 1 OPEN

Hi @hleiaa,

I remember this problem. TLDR; Please put all the macros in a file and configure mdBook-KaTeX to use it.

My attempt to add an option to process each chapter in serial to fix this: https://github.com/lzanini/mdbook-katex/tree/parallel-chapter-option.
It does not work in my testing.

In theory, if the same JS engine processes two blocks, it should remember what happened in the first block when running the second one. I thought that was the case because we use katex-rs, which has one JS engine per thread, but there seems to be something else wrong.

Maybe you could look a bit into this if you want, or consult the katex-rs people. I probably won't have time for major investigation until the end of next month.
