Unable to use this package from other packages

### What I would like to do:

 - Add the jar file to my own project
 - Import it to my own package
 - Create edf files

### Why it is not possible:

 - property `digitalValues`of class `EDFSignal` is package private, so it cannot be modified from outside of this package.
   - I didnt find any setter method for it

### Possible solutions

 - Make it public
 - Or add a setter method
