[boost] Request to merge bug fixes in Boost.Outcome

Can I get permission to merge a few small bug fixes plus docs fixes? https://github.com/boostorg/outcome/commits/develop 1. Changes just before the beta window breaks build on C++ 14 in certain corner cases, fixed. 2. Experimental Outcome Boost result did not compile due to changes to status code by LEWG, fixed. 3. Docs fixes also due to the LEWG renaming breaking docs examples. 4. Failure to compile Experimental Outcome on FreeBSD fixed. Niall
