With this commit the GUID encoding is now by default detected
automatically based on the validity of the version field,
and the timestamp (for time-based version 1 GUIDs).
The version is considered valid if it is 1 through 5.
The timestamp is considered valid if the year is past UNIX Epoch
and before the current year.

There are lots of BMC implementations that violate the IPMI
specification in regard to GUID encoding and instead encode
GUIDs according to either RFC4122 or SMBIOS specifications.
This commit restores the default behavior of `mc guid` to
SMBIOS-based decoding and adds options to allow for decoding
according to IPMI or RFC4122 specifications.
It also allows to simply dump the received GUID as is
without any parsing.
It is possible that in future versions `ipmitool` will
change default behavior to 'ipmi' instead of 'smbios'.
