Some dependencies are not present in this repository

Hi,

Some required imports are not present in this repository, nor included as a submodule or linked in the README

Specifically, this file with the following missing imports cause the build to fail:

import org.threeten.bp.YearMonth;
import org.apache.commons.lang.builder.CompareToBuilder;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

I obtained ThreeTen backport code from the following link:
https://github.com/ThreeTen/threetenbp

I obtained a specific version of the Apache commons-lang library circa Oct 2017 from this commit:
https://github.com/apache/commons-lang/tree/dd2394323b441e7a22d3c85ce751b619918ee161

I obtained Apache commons-io from here:
https://github.com/apache/commons-io

Obtained Simple Logging Facade for Java from here:
https://github.com/qos-ch/slf4j/tree/a8aa7832b7cb8091bc638d12a4fc1abfaaf44d8e/slf4j-api

...and finally got things building

As it was, this was a significant challenge to find all of these disparate imports and integrate them.

Seeing as they're all items mostly related to logging or datetime handling, is there any way you could remove these dependencies from the library? I doubt most users will need them, and their removal would likely make your library more portable. Parsing DTED files without a library such as this one is a significant challenge
