fix: fix issues

- fix BMapBindings generator due to the rename of LIBCMO_EXPORT -> BMAP_EXPORT.
- fix relative path issue in Python scripts within CodeGen.
- remove all references to LIBCMO_PANIC. use exception instead to tell user they are fool.
- basically finish universal encoding tables. add lost encoding name.
