Wasm Interface

According to the use cases of Slack bots, we define the following 5 functions for Wasm program to communicate with Host program. The 5 functions are as follows:

• text_received
• image_received
• expect_text
• expect_image
• initiate

If you implement a simple question-and-answer chat bot, you only need to implement the first text_received function.
