Make Traprange an internal library or remove it

[dougnoel]

Traprange is not available on Maven Central. We either need to remove it or make it part of the project.

Make Traprange an internal library under com.giabac.traprange.
Remove Traprange from the pom.xml

For now, create a traprange branch that includes it, then remove it from sentinel. It can be added back in later if needed. Otherwise the branch can be removed. All traprange does is allow you to view PDFs as tables when there are tables in them. It's very niche and has caused a lot of problems for a small feature.
