Malformed package.json refers to Index.d.ts which does not exist in npm package - cannot use package #32

The npm package doesn't work. This is because the package.json has

"main": "dist/src/Index.js",
...
"typings": "./dist/src/Index.d.ts"

but the captial-letter Index files currently exist only in this github repo's dist/ folder - they are nowhere to be found in the package obtained with npm i -D @fluffy-spoon/substitute. Presumably this is because of some renaming that occurred, after which the package.json didn't get updated. Really, it would be safer if this repo didn't have the transpilation result dist/ folder committed - this would help avoid such errors.
The package.json needs to be corrected in order for npm users to be able to use the package at all.
