This PR adds in some automation so that whenever the hashFiles.ts file or any json file within the src/Misc/expressionFunc/hashFiles/ folder is changed (meaning node dependencies), the host computer will interrupt and automatically run an npm run all to format, lint and package up the new javascript binary. It also will add that new binary to the latest commit for you so that no action is needed further.

This changes the workflow from

Make your changes -> `$ npm run all` -> `$ git commit {...}` -> `$ git push {...}`

to

Make your changes ->  `$ git commit {...}` -> `$ git push {...}`
