    odhcpd: update to Git HEAD (2025-10-02)
    
    b14cf98 router: log “Sending a RA on lan” at LOG_DEBUG
    c2810fe odhcpd: update cmake file
    8c2c065 odhcpd: convert README to markdown
    3b96480 odhcpd: allow the use of an alternative cfg file
    7328bfe odhcpd: remove confusing #defines
    cdb9e5b odhcpd: improve RFC9096 § 3.5 SLAAC compliance
    
    RFC9096 § 3.5 SLAAC compliance introduces a new config option (odhcpd
    piofolder), which may wear out the flash under certain conditions (for
    example: ISPs with dynamic IPv6 prefixes which disconnect the clients
    every X hours).
    Therefore, setting "dhcp.odhcpd.piofolder" to persistent storage in the
    router flash is not advisable and should be set to other kinds of
    persistent storage such as USBs, SDs, NVMEs...
    In order to prevent wearing out the router flash it's set to ephemeral
    storage by default (tmp):
      uci set dhcp.odhcpd.piofolder="/tmp/odhcpd-piofolder"
