Filtering of devices based on Skill ID

[NorthernMan54]

Description

I have found that users of your plugin and mine ( homebridge-alexa) have gotten themselves into a bit of a device adding loop, where each of plugins discovers the devices from the other plugin and keeps adding them. Eventually triggering a meltdown of homebridge due to too many devices being created.

To resolve this I made the following changes.

1 - Added your plugin name as the manufacturer of the Homebridge Accessory, this is to allow homebridge-alexa to filter out accessories created by homebridge-alexa-smarthome. A corresponding change will be made to homebridge-alexa to filter devices coming from manufacturer homebridge-alexa-smarthome.

2 - Added filtering of devices retrieved from Amazon, based on the skill id. The internal skill identifier is a base 64 encoded value, which contains the amazon internal skill id ie {"skillId":"amzn1.ask.skill.2af008bb-2bb0-4bef-b131-e191f944a87e","stage":"live"}

3 - Added trapping of errors coming from homebridge, when too many devices are created. A single instance of homebridge is limited to 149 devices.

4 - Added a feature to expedite testing, npm run test-watch. This is similar to npm run watch, except that it reruns jest on a code change.

PS This is a draft, take a look and send some feedback. It is also the first time I have encountered fp-ts so I likely mangled things around it.
