This pull request improves the compatibility with some Japanese encoding.
Problem
ruby-dicom 0.9.7 can't read dicom headers created by old dicom modality in Japan because these modalities specify character encoding 'ISO 2022 IR 13', 'ISO 2022 IR 13\ISO 2022 IR 87'.
Solution
Ruby can't read entire these encoding but part of these with encoding 'Shift_JIS'. So, this pull request proposes the new DICOM::ENCODING_NAME hash.
