Recommend dropping support for 0.2

[lance]

In the SDK requirements documentation, it says "Each SDK supports the latest(N), and N-1, major releases of the CloudEvent spec", with a special case being 1.0 as latest with 0.3 recommended support.

Ultimately, dropping support for 0.2 should make maintenance simpler. From npm download numbers, I guess it's hard to tease out how many are still on 0.2, but this seems reasonable.

I wonder also what the versioning strategy is. Is the npm module is versioned independently from the spec version? It seems like it must be - at least for minor and patch levels.

I agree in dropping 0.2 (and I support dropping 0.3).

@grant currently it is recommended that adapters continue to support v0.3. See: https://github.com/cloudevents/spec/blob/master/SDK.md#contribution-acceptance

I propose we follow the versioning of the most mature CE SDK, Go, and support v1 and v2.

However, this library needs a bit of work before then.
