I am not a maintainer

Would you fancy becoming it :slightly_smiling_face: ? I wanted to ask you for some time, feel free to say no if you see it as a burden but I'd really love to give you the freedom to apply changes and speedup the whole process :wink:

@facchinm

Would you fancy becoming it 🙂 ?

Well, yes! I would be honored. Really.

Note that I have only one Arduino on which I can test this library: an Arduino Micro. I thus cannot check cross-architecture compatibility. Is this a problem?

What would be the recommended way of handling the pull request then? Wait for the author to amend or respond to the feedback? Or push my recommended changes on top of his commit and then merge?
