Remove Node.js 7, add 10 and 11 (node)

[EwoutH]

Node.js 7 is out of support, 10 and node are the last stable long term support and the last stable versions.

This package does not yet support Node 10 but please see #32 which would bring support for it.

I plan on dropping support for all versions below Node 8 when Node 10 is supported as Node 8 is End-Of-Life this April.

Interesting enough it passes on Node.js 10 and 11, but fails on 6.

Shall I add a allow_failures to Node.js 10 and 11 for now?

[hannseman]

Looks like the failure on 6 is because of a linting error. No idea why it only fails on 6, never seen that before. I think that the tests passes on 10 and above is because the broken dependency is bluetooth-hci-socket and it's marked as an optional dependency by noble. The installation actually crashes if you look at the logs. The reason why the tests then are able to run is because noble is mocked away in the tests.

Good idea! Please add allow_failures to 10 and 11 if they would start crashing hard.

For full integration with GitHub you probably also need to enable Travis CI in the GitHub Marketplace.

I think you have an indentation error on the matrix-key causing a parse error on Travis CI.

Regarding the Travis CI github app we're stuck on their old environment travis-ci.org but I've emailed them about being migrated to travis-ci.com. See https://docs.travis-ci.com/user/migrate/open-source-on-travis-ci-com/#existing-open-source-repositories-on-travis-ciorg

I did a quick fix. Thank you for the PR!
