TI Wi-SUN FAN 1.0.7 release.

Tested with SimpleLink CC13XX CC26XX SDK
Q4 2023 release, version 7.40.00.xx.

Added the wisundirect and udp commands. For details on these features,
please refer to the README or help text.

Added hop limit control to ping and udp commands.

Ping, udp, and coap commands can take an EUI address as destination
address, automatically converting them into link-local IP addresses.

 wisunstack stop functionality is currently not implemented and will be done in future. Till then use 'reset' command to stop all operations and issue 'ifconfig up' and 'wisunstack start' to start the Wi-SUN network again.

+#### wisundirect
+Note that after enabling wisundirect on Border Router, PAN Configuration will no longer be transmitted.
+This is to ensure consistent bootstrap state for joining nodes.
+
+Turn Wi-SUN direct mode on. Off by default. Only intended to be used by Border Router devices. This enables a specific message header, allowing link-local unicast messages from the Border Router to be TX'ed and RX'ed properly by devices that are not fully joined. Both devices must have security exchange disabled (use preshared keys). wisundirect command should be called before interface/stack up.
+
+After calling wisundirect on, use ping or coap commands with a MAC address in the `<address>` field to send packets to a specific HW MAC address. Both devices must have exchanged at least one PAN advertisement solicit/PAN advertisement for this ping/coap command to go through.
