Log Message:
Update to tasty-1.4.1

Version 1.4.1
* Deduplicate command line options when there is more than one
  TestReporter. Expose the function that does that,
  uniqueOptionDescriptions.

Version 1.4.0.3
* Fix CPP warning/error macro expansion producing 'defined' has
  undefined behavior

Version 1.4.0.2
* Automatically disable the dependency on the clock package when
  compiled by ghcjs.

Version 1.4.0.1
* The only point of this release is to introduce compatibility with
  GHCs back to 7.0 (see https://github.com/feuerbach/tasty/pull/287).

  Note, however, that these changes are not merged to the master
  branch, and the future releases will only support the GHC/base
  versions from the last 5 years, as per our usual policy. To test
  with even older GHCs, you'll have to use this particular version of
  tasty (or have the constraint solver pick it for you when testing
  with older GHCs).

  The source of this release is in the support-old-ghcs branch of the
  tasty repository.

Version 1.4
* Change the TreeFold data type to give all functions access to
  OptionSet
* Fix a bug where a looping failure message escaped the time out set
  for the test
* Fix a bug where pattern changes inside the TestTree weren't
  respected

Version 1.3.1
* Add an ability for a test provider to print colorful/formatted
  output

Version 1.3
* IsOption has a new method showDefaultValue for customizing how
  defaultValues are rendered in the --help output.
* Drop support for GHCs older than 5 years
* Do not install handlers for the signals that dump core
* Export the AnsiTricks type/option
* In addition to a Parser, optionParser and suiteOptionParser now
  return a [String] representing warning messages:
  - A warning is emitted if an IsOption instance defines multiple
    options in the implementation of optionCLParser.
  - An warning is emitted if an IsOption instance's optionCLParser
    implementation assigns a default value (e.g., with
    Options.Applicative.value), as this interferes with tasty's
    ability to read environment variable arguments.
