Tidy up "Methods of accessing data and metadata"

Methods of accessing data and metadata

• Think about how this content fits into the book. Is this info relevant? What about STAC/intake to readers need to know?
• Could it be better named?

Our meeting was cut short last week and I came away unsure whether this is something I still need to address, or whether @paolap will tidy this up as part of #94?

sorry was away and then got sick, we thought we separate the actual resources as described in #94 from the tools themselves, so STAC and intake should be described as part of the software. I'm started on #94 if it helps you can wait until I push something??
