Scrape existing posts from the Wix instance

get_instance.sh gets an instance ID and saves it to instance.txt. Example: ./get_instance.sh

do.sh downloads the blog data using the instance ID from instance.txt and passes all its arguments to do_nonet.sh. Example: ./do.sh
do_nonet.sh optionally uses one argument named --cp-astro, which copies the output to ../huhuu-astro/src/pages/blog and passes the rest to draftjs_to_markdown.js. Example: ./do_nonet.sh --cp-astro
draftjs_to_markdown.ts optionally uses one argument, which if defined like the following only matches the specified post slug. Example: ./draftjs_to_markdown.ts --filter-post='1st-editorial-pääkirjoitus

./get_instance.sh
./do.sh --cp-astro --filter-post='violence-in-learning-environments-what-can-we-do'
./do_nonet.sh --cp-astro --filter-post='violence-in-learning-environments-what-can-we-do'
