"option[code]" extracts the value of the option with the given code
from the incoming packet. If the packet doesn't contain the option, it
returns the empty string. The string can be presented as text or hex
with the ".text" or ".hex" modifiers. In both cases only the payload
returns the empty string. The string can be presented as text or binary
with the ".text" or ".bin" modifiers. In both cases only the payload
is presented; the type code and length fields are not included.
