Minimum ABI warning

[wsfulton]

When running:

abi3audit --assume-minimum-abi3 3.4 --report -o example_abi3_report.json _example.abi3.so

I see:

[07:32:43] WARNING  no wheel to infer abi3 version from; assuming (3.4)                                                                                                                      _object.py:53
[07:32:44] 💁 _example.abi3.so: 1 extensions scanned; 0 ABI version mismatches and 0 ABI violations found                                                                                                 

It seems that this warning is pointless as I tell abi3audit to use a .so instead of a wheel and I tell it the minimum version to assume. Is either of these possible:

1. Can the warning be removed when using --assume-minimum-abi3 ?
2. Add in a warning control system for named/numbered warnings in the same way that compiler warnings can be individually turned on and off, like the -W family of options in gcc?

IMO it'd be useful to keep around as a DEBUG and not a WARNING (since it helps me root-cause user reports), but I agree that it's pointless as a warning when the user explicitly sets --assume-minimum-abi3.

Would you be interested in sending a PR for that? Otherwise I'll likely get to it today or tomorrow.

I might just leave this to you if you don't mind as I don't quite understand if you'd prefer a warning instead of debug when --assume-minimum-abi3 is actually set.

if you'd prefer a warning instead of debug when --assume-minimum-abi3 is actually set.

Yeah, I was thinking an unconditional DEBUG (since it's still useful information to have when debugging). But I'll do this one.

Done with #103. Let me know if you'd like a release for this, otherwise I'm likely to do it when the next round of feature changes happens!

Thanks. No rush for you to make a release from my side.
