Add SPD, ATTR, and code support for thermal sensor fields

In order to not break systems with old DDIMMs or old Explorer FW,
this commit includes a workaround to bypass the thermal field parsing
if the SPD revision is less than 0.3, as the decoder will try to
parse garbage. This can be replaced down the line if needed with
a proper API.
