subscribe() for ConsumedThingProperty about node-wot

[mkovatsc]

For now at least a placeholder that provides a meaningful error ("not implemented").

It seems to me that subscribe() did get implemented in the meantime, but it fails to work with coaps (I'm using good old Trådfri lamps).

Here's what I was able to figure out: ContentSerdes.contentToValue() expects the content to have field body. read and invoke do provide content.body to the callback. However, subscribe calls coaps.observe(), which results in the response message from CoapClient to be sent directly to next callback, bypassing the conversion as in read and invoke.

Result: Parsing error at codec.bytesToValue(), because content.body is undefined.

The fix for coaps is simple enough, but I don't know how well it will play with all other bindings, hence no PR.

quick question: which node-wot version are you using?

Is this issue still unresolved even after the new Scripting API changes/updates?

HTTP is fixed by #233 while CoAP has been fixed before.
