pho a42b33a614 Update to random-1.2.0
* Breaking change which mostly maintains backwards compatibility, see
  "Breaking Changes" below.
* Support for monadic generators e.g. mwc-random.
* Monadic adapters for pure generators (providing a uniform monadic
  interface to pure and monadic generators).
* Faster in all cases except one by more than x18 (N.B. x18 not 18%)
  and some cases (depending on the type) faster by more than x1000
* Passes a large number of random number test suites:
  - dieharder
  - TestU01 (SmallCrush, Crush, BigCrush)
  - PractRand
  - gjrand
  - See https://github.com/tweag/random-quality for details on how to
    do this yourself.
* Better quality split as judged by these tests:
  https://www.cambridge.org/core/journals/journal-of-functional-programming/article/evaluation-of-splittable-pseudorandom-generators/3EBAA9F14939C5BB5560E32D1A132637
  Again see https://github.com/tweag/random-quality for details on how
  to do this yourself.
* Unbiased generation of ranges.
* Updated tests and benchmarks.
* Continuous integration.

Breaking Changes

Version 1.2.0 introduces these breaking changes:
* requires base >= 4.8 (GHC-7.10)
* StdGen is no longer an instance of Read
* randomIO and randomRIO were extracted from the Random class into
  separate functions

In addition, there may be import clashes with new functions,
e.g. uniform and uniformR.

Deprecations

Version 1.2.0 introduces genWord64, genWord32 and similar methods to
the RandomGen class. The significantly slower method next and its
companion genRange are now deprecated.
