Add image compression in automation

[TamimiGitHub]

in the ./export.sh script, include a step to iterate over all the assets in the img dir and compress all the images
For example
https://www.npmjs.com/package/compress-images

Notes:

1. Once an npm package is installed, the cli executable can be accessed from node_modules/<name_of_package>/bin
2. Rename compressed images to -compress. (or similar) to avoid recompressing already compressed images
3. Add exception handling to image extensions that is not supported by the compression cli tool. There are alot of weird extensions for images

two thoughts:

1. If you rename the files to add -compress on the end you also need to rename them in the markdown as well
2. Before actually implementing this it would be good to do a quick comparison of a compressed png or jpeg vs. conversion to webp to see if there is a large different

Ah good point.

1. We can mitigate the file rename with an update of the metadata of the file to add a compressed=true flag, or something along the lines
2. Benchmarking is a good idea 👍 thanks
