Add up to 8 entries for CPUID leaf 04; push version to 0.3.0.

Browse source 
This is a backwards-incompatible binary change, which increases
sizeof(cpu_raw_data_t). Specifically, the cpu_raw_data_t::intel_fn4
array is increased from 4 to 8 elements, because on recent Hasells
(Crystalwell) there is a Level 4 cache, which should be encoded in
CPUID eax=4 ecx=4. However, we were only storing levels for eax=4
for ecx <= 3. Thus the raw data didn't have the relevant info.

There will be further changes to this, specifically to store
and print the level 4 cache in cpuid_tool.
