This has been bounced around for a couple years now
#474 and a few others have expressed desire to work with non-standard
option names. We have been somewhat resistant to that but I think it can
be done now. This PR adds a modifier `allow_non_standard_option_names()`
It is purposely long, it is purposely off by default. But what it does
is allow option names with a single `-` to act like a short option name.
With this modifier enabled no single letter short option names are
allowed to start with the same letter as a non-standard names. For
example `-s` and `-single` would not be allowed.

Also works for overloads constrained with concepts or requirements.
Previously this wasn't working, which is a problem if you want to hook
some external serialization framework into CLI11 without painstakingly
going through all the types that said external framework supports.
This PR is related to https://github.com/CLIUtils/CLI11/issues/908.
* Add the beginnings of a fuzzing system for CLI11. This commit adds the fuzzing code, a simple test, and two fixes to issues(seg faults) found by the initial round of fuzzing. It also adds a few tests and coverage issues uncovered in the process of developing the fuzz tests. As a side effect adjusts some of the azure tests to specify the vmImage which was being changed on azure.
* update license to match rest of code base

* Update options.md book chapter and the readme to better reflect current usage and the modifications to the add_options templates.
add support in add_option for wrapper types, such as std::optional, boost::optional or other types with a value_type trait. Add support for generalized containers beyond vector, add support for nested tuples and vectors, and complex numbers directly in add_option. This includes several new type traits and object categories.
Upgrade the google test version to better support templated tests.
add support for vector argument separator `%%`
* update formatting to match recent changes
* Apply suggestions from code review
