buf.includes(value[, byteOffset][, encoding])
Operates similar to Array#includes(). The value can be a String, Buffer or Number. Strings are interpreted as UTF8 unless overridden with the encoding argument. Buffers will use the entire Buffer (to compare a partial Buffer use buf.slice()). Numbers can range from 0 to 255.
The byteOffset indicates the index in buf where searching begins.
