This is an example of a client application which uses this library to generate
a message with a table within a specific Microsoft Teams channel.

Of note:

- default timeout
- package-level logging is disabled by default
- validation of known webhook URL prefixes is *enabled*
- message is in Adaptive Card format
- text is unformatted
- a table with headers is added to the message

See https://docs.microsoft.com/en-us/adaptive-cards/authoring-cards/text-features
for the list of supported Adaptive Card text formatting options.
