If data is dictionary send it as form data

[FoamyGuy]

In python3 with requests we can use code like this:

import requests
URL = "https://docs.google.com/forms/u/0/d/e/1FAIpQLScoUhFA1BIJjXF2-QM_mxNMN62Y2BCJ--gwJIwWcwJPvWDlwQ/formResponse"
form_data = {
    "entry.2004206042": "Hello",
    "entry.487209416": "Binka"
}
r = requests.post(URL, data=form_data)
print(r.text)

And the data will get sent as form data. More specifically using the format:
name=value&other_name=other_value

and gets sent using Content-Type: application/x-www-form-urlencoded

This allows us to use a simple dictionary for our form data but submit it to web apps expecting data from an html <form> element.

This change allows the circuitpython requests library to behave similarly. When data is a dictionary it will get formatted into the key/value string and sent with Content-Type: application/x-www-form-urlencoded

With this change we can use almost the same code for python3 and CircuitPython to post data to Google forms/spreadsheets and and similar <form> based web apps.
