Thanks for the PR. I'm not sure of the value of adding a new environment for CC1101 and an ESP8266 based board, as we have already nodemcuv2-rf-cc1101

Do you know that you can store your environment into a prod_env.ini file separate from environments.ini ?

@1technophile yep, prod_env.ini is exactly how I'm using it right now. The reason for the PR is that nodemcuv2-rf-cc1101 appeared to be incompatible with Wemos D1 mini boards as-is, so I thought dedicated env could be helpful for people who are using D1 mini board.

I'm ok with any decision from your side however.

Let's add it as an example only in this case (commented)

@1technophile I've moved D1 mini example to the prod_env.ini.example file
