Small improvements to the docs

[colinbrislawn]

On this page, https://seekdeep.brown.edu/illumina_paired_info.html#overlap-status

The image shows

1. R1EndsInR2; first mate ends in the second mate
2. R1BeginsInR2: “read through”
3. NoOverlap

But the text descriptions says

1. no overlap the sequences do not overlap
2. first mate ends in the second mate
3. first mate begins in the second mate (in this case the primer/adapters from the other ends are sequences, a scenario referred to as “read through”)

These different orderes make it hard to point to a specific example. Is 3. NoOverlap or ReadThrough??

If you point me to the location of the docs, I can make the text match the image.

Thank you!
