Could customSnapshotDir be a callback?

[velvet-dream]

As suggested here in this issue #62

It would be really useful to have customSnapshotsDir specified as function, in order to have much more flexibility over the way snapshots are stored, and make it possible to generate path on the fly depending on testPath, etc.

{ customSnapshotsDir: ({currentTestName, testPath}) => buildCustomSnapshotDirOnTheFly(currentTestName, testPath) }

In my usecase, we have our own framework with our React components. There are many components, and I would like to get all the snapshots stored in the same directory, with a structure identical to that of the framework. Something that would look like this:

root/
├─ snapshots/
│  ├─ inputs/
│  │  ├─ button/
│  │  │  ├─ button-snapshot.png
│  │  ├─ inputNumber/
│  │  │  ├─ inputNumber-snapshot.png
