Fantomas 4.4.0

This library aims at formatting F# source files based on a given configuration.
Fantomas will ensure correct indentation and consistent spacing between elements in the source files.
Some common use cases include
(1) Reformatting a code base to conform a universal page width
(2) Converting legacy code from verbose syntax to light syntax
(3) Formatting auto-generated F# signatures.
