Description
This is related to #236. Brittany currently passes instance heads through. For example:
-- brittany --columns 20
instance SomeVeryLongConstraint => SomeVeryLongTypeClass SomeVeryLongType
I'd expect that to be formatted something like this:
instance
SomeVeryLongConstraint
=> SomeVeryLongTypeClass
SomeVeryLongType

Research direction
Start by reading the related issue #236 and locating the formatter logic for Haskell instance declarations; the issue names no source files or tests. Reproduce the example with a small input using --columns 20, then verify that long instance heads wrap into the shown multiline layout without changing other formatting.
