Invalid feedname results in no error client or server side

[askpatrickw]

I was doing this...

_mqtt_key = f"{aio_username}/feeds/{feed_name}"
aio.publish(_mqtt_key, value)

instead of

aio.publish(feed_name, value)

And I got no error client side or in the io.adafruit.com monitoring page.
Took me forever to figure out why it wasn't working... :-)

@askpatrickw I can confirm this occurs when attempting to publish to io.publish("brubell/feeds/temp", 1) and also with subscribe client.subscribe("brubell/feeds/temperature").

This library should perform validation across any method which access feed keys using the following rules via https://learn.adafruit.com/naming-things-in-adafruit-io/the-two-feed-identifiers:

1. The only characters we permit are lower case English letters ("a" to "z"), numbers, and dash ("-").
2. The name must be a maximum length of 128 characters.
