1.18 worth.yml file

The worth.yml file is fully up to date at this time for 1.18, pending any new bugs found.

updated 1.18 worth.yml including item_names with separators

I have merged in #64 to the spreadsheet and will release the new version of both the yml file and the spreadsheet.

Additionally I have cleaned up some of the tabs in the spreadsheet and reorganized them.

worth file updated to include Minecraft 1.17 items

This release will include the items from 1.17 and a new worth file that includes the underscore separators between words (hopefully)

worth file updated to include Minecraft 1.16 items

all remaining 1.16 added items have been added and valued. as far as I can tell.

initial release based on Minecraft 1.15 items

not all there, not entirely sure what is missing. but it should be a fully functional worth file, with a few bugs caused by Google Sheets
