Split fat macho into own decoder macho_fat. This also fixes issue with section
offset etc not being correct as they are from the start of each embedded file.
Make all address and offset field be in hex.
Decode __cstring, __ustring and __cfstring sections.
Fix LC_ENCRYPTION_INFO_64 missing pading issue.
Skip ranging for __bss and __common as they dont have any data in the file.
Simplifed magic handling a bit and add symbols.
Simplified state struct field, had redudant struct.
Doing it thru a propery in the decode fn feels a bit hidden and will
also not get set on failed decoding.
Now array is not range sorted, logic is you care about index number and ordering.
Struct is range sorted as you will prefer to fields by name.
Some formats might want to control child order
mp4: Keep tracks in track id order
dns: Keep label component order
elf: Keep seciton order
macho: Keep command and section order
