FEAT: JHOVE ready TIFF library

- factored lower level TIFF reader so that it supports different data source methods (e.g. input stream, file, etc.);
- added a slightly hacky set of methods so that file paths not required for TIFF validation;
- took OPF ownership of Maven publication for permissions; and
- added myself to the developer list.
