🚀 Add LICENSE.txt File

[Francewhoa]

Is your feature request related to a problem?
Hello @tobimensch & all other contributors to blahdns :) What is blahdns license?

Describe the solution you'd like

To potentially attract more contributors, more donations, and for a stronger security & privacy, I suggest adding a LICENSE.txt file to this repository

If you're not familiar with a license file, the following free tools might be useful to easily & quickly choose one, then create the license file

• https://choosealicense.com

• https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/customizing-your-repository/licensing-a-repository

Feel really free to choose any type of license to your liking. If not sure about which type of license file to choose, I suggest this GNU GPL 3. So that you are protected from Liability or Warranty claims. While at the same time, as primary author, you remain fully free to edit your code in any ways to your liking, within the GPL3. Another benefit with GPL3 is that you would remain fully free from external interferences.

Any volunteers to create a license file?
