Support for CoAP extended options

Type: bool

Help

This option enables the parsing of extended CoAP options length.
CoAP extended options length can be 2 byte value, which
requires more memory. User can save memory by disabling this.
That means only length of maximum 12 bytes are supported by default.
Enable this if length field going to bigger that 12.
