bug: instant send doesn't work in browser

Browser shim for request should properly encode json and forms.

What was the specific method, url, and error @jojobyte?

This code appears to be broken: https://github.com/dashhive/dashsight.js/blob/main/dashsight.js#L144-L154

And the description here https://github.com/therootcompany/request.js#requestoptions-callback may need to be updated for json
