Add support for different flow styles in Sequences

[bristermitten]

This adds support for the Flow Style of rendering Sequences, by adding a parameter to YamlConfiguration

The default block style is still used to avoid breaking anything.

This is referenced in #33

Hey @knightzmc, thanks for the PR. It looks like the formatting check is failing - could you please run ./gradlew spotlessApply to fix any issues and push that change?

[charleskorn]

In fact, it looks like your IDE might have reformatted the test file - could you please revert the unrelated changes so that it's clear what you've changed?

[bristermitten]

Oh, that's weird. When I ran the tests it told me that spotless had failed so I formatted it. Must've accidentally changed something

[bristermitten]

@charleskorn I ran spotless again, it seemed to have fixed all of the formatting issues.

Thanks again for this PR. It looks good to me - there are only two minor things and then I think this should be good to merge.

[bristermitten]

Hi @charleskorn I've gone through the diff and reverted all of the accidental test changes, along with adding a simple doc

[charleskorn]

Looks great, thanks again for the PR @knightzmc!
