Context extension: What's the replacement?

[philvarner]

From @m-mohr:

Came up in Gitter today, but I can't open issues in the context extension so doing it here so that we can keep track:

We should give a hint in the context extension readme what the actual replacement for the context extension is.

Hi, we recently bumped into the fact that the context API extension (https://github.com/stac-api-extensions/context/) was deprecated (47ee1d3). Does somebody know (1) why it was deprecated and (2) what should be used to replace it?

We should probably add a note to the README that explains what should be used instead.

Quick recap:

1. OAFeat offers the same functionality so we aligned with them
2. Which means that you just use what is used in OAFeat (i.e. the fields numberMatched, numberReturned etc)
