[Anupam Roy <anupam.r@xxxxxxxxxxx>]

This patch accepts 16 octet hex key for static OOB authentication

[mesh-cfgclient]# provision F24B3F329DF200000000000000000000
Provisioning started
Request hexadecimal key (hex 16 octets)
[[mesh-agent]# ] Enter key (hex number): 0a0b0a0b0a0b0a0b0a0b0a0b0a0b0a0b
Assign addresses for 4 elements
Provisioning done:
Mesh node:
    UUID = F24B3F329DF200000000000000000000
    primary = 00aa
    elements = 4
