c6d0e5a93d DPP2: Add E-id in Reconfig Announcement 
Add an encrypted Enrollee identifier into Reconfig Announcement frames
and decrypt that on the Configurator side. The actual E-id value is
currently not used for anything, but it can be used in the future to
provide better control over reconfiguration.

e5be6e68c8 DPP2: Add Enrollee netAccessKey group into Reconfig Announcement 
This was added to the protocol design to support cases where the
C-sign-key uses a different group than the netAccessKey. The Enrollee
now indicates its netAccessKey group in Reconfig Announcement and the
Configurator builds it own reconfig Connector using that group instead
of the group used for the C-sign-key.
