Option to disable for imported libraries

[electrofelix]

Given that underscores are common in protobufs, particular around enums, where the following definition from https://developers.google.com/protocol-buffers/docs/proto3#enum:

message SearchRequest {
  string query = 1;
  int32 page_number = 2;
  int32 result_per_page = 3;
  enum Corpus {
    UNIVERSAL = 0;
    WEB = 1;
    IMAGES = 2;
    LOCAL = 3;
    NEWS = 4;
    PRODUCTS = 5;
    VIDEO = 6;
  }
  Corpus corpus = 4;
}

Will in generated code resolve to CORPUS_UNIVERSAL, CORPUS_WEB, ....

It would be useful to be able to ignore all instances such as this coming in from specific imported libraries where the consuming project does not have control over the naming. As we make use of protobuf and enums, I've had to disable the linter as there are no many occurrences of this caught, while I would prefer to leave it to catch the odd mistake automatically.

In my opinion the linter should actually only check new declarations and type definitions in the current project. I'm not aware of any linter that flags issues that stem from other dependencies. Currently nosnakecase even flags stuff from the standard library such as the constants from x/sys/unix.
