Add page for spv3-manual #32
Description
https://github.com/HaloSPV3/spv3-manual
I'm thinking about adding this to halospv3.github.io so we have an online viewer for it.
A. Merge the project into halospv3.github.io. The source files can be completely converted to FrontMatter-format Markdown with embedded/raw html tags where Markdown is in sufficient. Most Markdown renderers support this.
B. Add it via Git Submodule in halospv3.github.io. spv3-manual's files can probably be referenced and copied or embedded into the compiled website. Git submodules are a pain to work with if you don't use a GUI that makes it easier. I can attest to VSCode and SmartGit making submodules easy to work with.
