コントラクト

• NimbleCSV.RFC4180.dump_to_iodata selectively quotes and doubles escape characters only for fields containing reserved delimiter, escape, or newline characters, while leaving empty strings and unreserved fields bare.
• assert dump_to_stream lazily emits each row as iodata with CRLF row terminators
• assert custom parser defined with :reserved forces quoting for configured characters such as spaces and hashes
• assert parse_enumerable preserves multiline quoted fields across enumerable elements and respects skip_headers
• assert streaming rows through dump_to_stream and converting iodata chunks to binaries roundtrips losslessly through parse_enumerable
