Suggestion: Change "Pallete" to Node

[nileio]

Hi @VolodymyrTymets .. thanks for providing this excellent example. I was looking for something similar.
In order to align terminology and language to NodeRED , I think you may need to revise the use of the word "Pallete".. It is not really used by the project and also is a little bit confusing to be honest. I suggest refactoring and use NodeManager instead of PalleteManager, Node instead of Pallete, etc.

I am going to use your code as basis for my own, and this will be the first thing I'd change.
Thanks 👍
