The dual16 mode is now fully encoded in the disassembly output through
type suffixes (:f16 vs :f20) and register naming (th vs t), making the
explicit dual16 mode parameter redundant.
Previously, the parser needed a dual16_mode flag to determine whether
float immediates should use imm_type=0 (f32) or imm_type=3 (f16). Now
that the disassembler emits explicit :f16/:f20 suffixes, the parser can
determine the correct encoding directly from the input text.
This simplifies the API by removing the dual16_mode parameter from:
- isa_parse_str()
- isa_parse_file()
- Internal parsing functions
