Extend RemoteUnwinder to capture precise bytecode locations

Browse source 
Introduces LocationInfo struct sequence with end_lineno, col_offset, and
end_col_offset fields. Adds opcodes parameter to RemoteUnwinder that
extracts the currently executing opcode alongside its source span.

Refactors linetable parsing to correctly accumulate line numbers
separately from output values, fixing edge cases in computed_line.
