* Prepared skeleton and basic component implementations for the jbig2 encoding. * Added Bitset. Implemented Bitmap. * Decoder with old Arithmetic Decoder * Partly working arithmetic * Working arithmetic decoder. * MMR patched. * rebuild to apache. * Working generic * Decoded full document * Decoded AnnexH document * Minor issues fixed. * Update README.md * Fixed generic region errors. Added benchmark. Added bitmap unpadder. Added Bitmap toImage method. * Fixed endofpage error * Added integration test. * Decoded all test files without errors. Implemented JBIG2Global. * Merged with v3 version * Fixed the EOF in the globals issue * Fixed the JBIG2 ChocolateData Decode * JBIG2 Added license information * Minor fix in jbig2 encoding. * Applied the logging convention * Cleaned unnecessary imports * Go modules clear unused imports * checked out the README.md * Moved trace to Debug. Fixed the build integrate tag in the document_decode_test.go * Applied UniPDF Developer Guide. Fixed lint issues. * Cleared documentation, fixed style issues. * Added jbig2 doc.go files. Applied unipdf guide style. * Minor code style changes. * Minor naming and style issues fixes. * Minor naming changes. Style issues fixed. * Review r11 fixes. * Integrate jbig2 tests with build system * Added jbig2 integration test golden files. * Minor jbig2 integration test fix * Removed jbig2 integration image assertions * Fixed jbig2 rowstride issue.
