Figure out how to support projects with weird section ordering

Like starfox 64, which does text, data, rodata, data, rodata, data, bss
https://github.com/sonicdcer/sf64/blob/master/yamls/us/main.yaml

Or rocket which goes
```
boot - [boot stuff]
codeseg1 - [rodata1, text1, data1]
codeseg2 - [rodata2, text2, data2]
bss - [bss1, bss2] 
```
