remove jquery stuff

[jimmywarting]

I think this tool should be as vanilla as possible and only do one thing web workers, node and deno don't need this unnecessary stuff

that means removing this jQuery bit https://github.com/mholt/PapaParse/blob/5747da6c9927642743d6d44d49689be2d2fa0b10/papaparse.js#L87-L179

most ppl have moved away from the good old days of jquery now where MVC have taken over such as vue, angular, react, sapper etc
