v7.0.0

Breaking changes:

• Migrate FFI to ES modules (#86 by @kl0tl and @JordanMartinez)

Other improvements:

• Replace all usages of F and FT with Except/ExceptT (NonEmptyList ForeignError) (#87 by @JordanMartinez)

  Often times, the F and FT aliases did more to hinder usage of this library than help. These aliases
  haven't been deprecated, but usage of them is now discouraged. All code in the library now uses
  the full type that is aliased by F and FT.
