Add a webserver to smibhid for admin purposes

[sjefferson99]

For #240 and #241 we need a webserver to provide an admin interface. Issue is to investigate adding one to the async loop and see if it can be supported without first implementing MQTT.

I have a webserver from another project I will integrate based on tinyweb that I know works in a similar async loop.
