Add esp8266-based diy pushbutton

[yun14u]

I have been building my own esp8266-based device using esp01 and with amazon-dash, it works very well.

Hello @yun14u ! Can you add any additional information to the documentation? Thanks!

There are many youtube videos in related on building DIY pushbutton using esp-01. Please point me to the section where you want these information to be referenced and I will update them.

I would appreciate it if you could add a new page in the documentation for this: https://github.com/Nekmo/amazon-dash/tree/develop/docs

I don't have an ESP8266 to test so I can't document the process. I could search for documentation but it could be wrong or even dangerous for users.

Written documentation can be read online, for example: https://docs.nekmo.org/amazon-dash/block_connections.html

I built my own DIY push button. I might include a tutorials/YouTube references on how to build a DIY esp01-based push button in the documentation. IMO, building a this diy button is not in the scope of amazon-dash.
