add version to payload

[tomkralidis]

It would be valuable for a CoverageJSON payload to identify conformance (similar to OGC API - Records. Example:

{
    "conformsTo": [
        "http://www.opengis.net/spec/covjson/1.0"
    ],
    "type": "CoverageType",
        "domain": {
            "type": "DomainType",
    ...

While clause 10 of the DP provides guidance on further qualifying the media type with conformance, would it also be valuable to add to the payload itself (to self identify independent of the transfer mechanism)?

Yes, I think that's a sensible idea. This could maybe go into v1.1. I guess it would have to be optional or "strongly recommended" in order to preserve backward compatibility.

+1. PR in #163 (not sure if master branch is still 1.0 bound).

@tomkralidis @jonblower We had better leave Master Branch as V1.0 until @ghobona confirms it is published and we can make master v1.1 (or V1.0.1).
