Please implement autodisconnect timeout setting

[osos]

Some users experience bad battery life on the flic buttons.

A suggested solution from Flic is to set the autodisconnect timeout to 15.

See 50ButtonsEach/fliclib-linux-hci#50

Also possible from NodeJS. See https://github.com/50ButtonsEach/fliclib-linux-hci/blob/beca86dc0953bc4c56051fa65dc536edea45e5eb/clientlib/nodejs/fliclibNodeJs.js#L475

@Roaders If you have a moment to look at this that would be great as I'm without broadband for the next few weeks.

Sorry, I don't have time to look into implementing this at the moment. Right at this moment I am on holiday in Iceland but even when I get home I don't have enough time to work on my own projects let alone anything else.
I would look at a pull request...
