novoSite: tidying up the repository

[vugonz]

I believe we should start the revamp by tidying up the repo.

I think it would be a good idea to remove duplicate images that are distinguished as "before compression" and "after compression" and only track images which are used in the website.

Following this, I also think it would be better to move scripts, such as compression ones, to a scripts/ folder and, if necessary, create tiny python packages for them, or a medium sized package which supports all tools, so that they can work over time (or simply state the python version at the start of each script).

Also, remove files which I believe are being tracked by mistake, such as .hugo_build.lock or sqlWorkbench.mwb.bak and add them to .gitignore

LMK your thoughts
