[Feature Request] Dump as lines

[tinder-garricnahapetian]

I love using swift-snapshot-testing. So thank you! I love using the .dump strategy. Sometimes, the value I'm snapshotting contains long strings. Long strings can be hard to read when using .dump, especially when the string contains many new lines. Would it be possible to add a strategy that is a combination of .dump and .lines. It would work just line .dump expect that strings would be snapshotted within the .dump as .lines.
