[BUG] Object files are grouped into the same family even if targeting different functions

[NWPlayer123]

Describe the bug
This is mostly a consequence of objdiff's decomp.me integration. Since it uploads the entire TU as a .o, decomp.me will treat all scratches as the same family even if the user is trying to diff a different function

To Reproduce
Import two different functions from the same TU using the 📲 decomp.me button in objdiff

Expected behavior
Functions to be treated as different even if they use the same .o as the diff label is different and it hides all asm but the one being targeted, so a normal user would just see the function they're working on without it being grouped with other functions in the same TU.

Additional context
Relevant Discord discussion
Something else to think about, per @1superchip (link), more flexibility in family might be good, or finally rolling out game-specific projects as was experimented with on Paper Mario 64 as it would allow grouping together multiple platforms
