RFC for parse result link relations

[smizell]

This is an RFC for link relations for the parse result namespace.

Distilling my comments from our Slack conversation:

1. I am still a little uncomfortable with the inferred link relation. It just doesn't feel like a link to me, but I won't block this because I don't have a better solution that is as generic as this one. A property on meta called inferred is very specific to this particular use case.
2. The origin relation makes sense to me since it is a link to the originating software. I like this.

So, given we get some other eyes on this (@Almad, @zdne, etc.) then I am okay with merging.

[zdne]

I am OK with this once #22 is resolved.

@danielgtaylor

It just doesn't feel like a link to me,

I think it is good if the inferred points to the author (tool) of the inferred element, so I think it could (read should) be a link

Merging with #22 being active
