A dynamic buffer encapsulates memory storage that may be automatically resized as required, where the memory is divided into an input sequence followed by an output sequence. These memory regions are internal to the dynamic buffer, but direct access to the elements is provided to permit them to be efficiently used with I/O operations, such as the send or receive operations of a socket. Data written to the output sequence of a dynamic buffer object is appended to the input sequence of the same object.

Removes `n` bytes from beginning of the input sequence. If `n` is greater than the size of the input sequence, the entire input sequence is removed. All constant or mutable buffer sequences previously obtained using `data()` or `prepare()` are invalidated.

Throws: `length_error` if `size() + n` exceeds `max_size()`.
