Add docs for how to build a new image

[decentral1se]

Seen from https://github.com/Tenrec-Builders/pi-scan/blob/master/make/README.md, we know that there is a build process to produce a new image but it is not clear how to do that process immediately. I remember messing with debian packaging and chroots before and ending up with getting into difficulty for some $reason on my host computer with mounts. I'd really appreciate some instructions for producing a new pi-scan image.

The build process is just a variant of the pi-gen system for making normal Raspberry Pi images. This has been mostly a one-person project and so there was little need to urgently publish the build process. But if there is interest , I can create a resository for the build scripts that is publicly available. In addition to these issues, you have also emailed me personally. So ping me when you are comfortable with the vanilla pi-gen process and I'll link you the repo for building these variant images.

I started working on this here: https://github.com/abevoelker/pi-gen

I got pretty far, however currently Pi Scan is failing to start due to this error:

lupa._lupa.LuaError: [string "<python>"]:2: module 'chdkptp' not found:

It seems to be an issue reported with chdkptp.py:

• Python3.6 compatibility  jbaiter/chdkptp.py#6 (comment)
• I found that the encode=None at the lua runtime was the cause of the issue, but now I can't install the package. jbaiter/chdkptp.py#12

However I'm not sure how to resolve it at the moment. python --version is 2.7.18 so it shouldn't be a Python 3 issue (I think).

Okay I got past that error. Very weird but apparently pip install wasn't running chdkptp.py's setup.py instructions to build chdkptp.so, so it couldn't be found. I switched to python setup.py install and it works and Pi Scan is booting up now. Haven't tested actually scanning anything yet though

Thanks for your work on this! It's hugely appreciated. g.
