/**
 * Use this script to create an importable json file from any table on DnDBeyond.
 * Author: @Krishmero#1792
 *
 * How to use this script.
 * 1. Right click on the table you wish to extract. Inspect element and grab the table id or the data-content-chunk-id
      Should be something like <table id="table016" class="Table TableOverride-1">
      OR <table class="compendium-left-aligned-table" data-content-chunk-id="85e84434-84db-4247-a0da-b00a556756f2">
 * 2. Open Chrome console window (F12) & go to the Sources Tab -> Snippets -> new snippet and paste this file in there.
 * 3. Run snippet (ctrl+Enter for windows). Json file to import will download.
 * 4. In foundry, make a new rollable table, then right click it on the sidebar and do an import.
 * 5. Import the downloaded file & celebrate.
