Rebrand as NodeCore EP9x, document

We've settled on "EP3x twice" as the algorithm choice that gives
the best overall results across the variety of artwork present.
Name the package after this and explicitly document the algorithm
choice.

We could still conceivably explore other options, like the HQX or
xBR families, in other branches, using the same infrastructure, but
to be published to CDB, they'd require different naming/branding.
