Reword ink-layer copy: candidates for expert reading

Replace claims that neural networks found the ink with: ink layers
show where models detect ink; letters visible here are candidates
for expert reading. Updates the README, page lede, meta tags, and
the PHerc0139 manifest lede.

 # Unroll
 
-PHerc. 139 is a papyrus roll carbonized when Vesuvius buried Herculaneum in 79 CE. It cannot be opened, so it was scanned with X-rays at the ESRF synchrotron. This page rebuilds 37 of its windings in 3D from the public Vesuvius Challenge meshes and lets you unroll them in the browser, with the ink that neural networks found on them.

 - **X-ray layer**: the CT intensity on each surface, from the public 9.362 µm surface volumes.
