[KostadinAlmishev]

Fixes #130

To indent entire array when indicatorIndent != 0, to printer should be passed indentWithIndicator = true

Thanks for the submission, but it looks that change won't be binary compatible.... What needs to be done is deprecating Config and the current make function and creating a new ConfigBuilder, similar to what Ember does here: https://github.com/http4s/http4s/blob/00fcd90fcd26259026908dd4e1bff853432ac3f0/ember-client/shared/src/main/scala/org/http4s/ember/client/EmberClientBuilder.scala#L44. With the builder pattern we'll be able to add options compatibly going forward!
