Custom snapshots path

[AllDmeat]

Context 🕵️‍♀️

Our project structure is split into bunch of modules with same structure like this:

ModuleName
├── Sources
└── Tests

We've been using swift-snapshot-testing for quite a while, but without Prefire. swift-snapshot-testing saved snapshots into Tests folder, so structure actually was like this:

ModuleName
├── Sources
└── Tests
    └── __Snapshots__

What 🌱

We started writing tests using Prefire, but it stores snapshots in a different location. So now we have two folders with snapshots:

ModuleName
├── Sources
├── Tests
│   └── __Snapshots__
└── ModuleNameTests
    └── __Snapshots__

Proposal 🎉

While the case totally isn't a critical one it still would be great to have a way to customize path for generated snapshots or to match with swift-snapshot-testing defaults.
