Elementary writing of a string to a buffer

The target is of type *buffer.Bytes and the string is simply written to it. An elementary case is considered. Any formatting or processing makes this benchmark irrelevant. This module is using methods writing a string without conversion.

• fmt.Fprint
• WriteString() method of buffer package
• io.WriteString()

As fmt offers more possibilities, it takes about 3x the cost as others.
