* Add benchmark for cbor serialization and cbor binary data serialization
* Use std::vector::insert method instead of std::copy in output_vector_adapter::write_characters
This change increases a lot the performance when writing lots of binary data.
* Add overloads for more key types to ordered_map
Add overloads to accept additional key types defined by type trait
detail::is_usable_as_key_type to ordered_map.
The same key types that can be used with json can now also be used with
ordered_json.
* Fix ordered_map::erase(first, last) with first == last
* Modify element access unit test to also test ordered_json
Use DOCTEST_* macros in place of predefined compiler macros for compiler
detection and version checks.
The suppression of warning -Wrange-loop-construct in unit-items.cpp
causes GCC<11 to warn about pragmas. Suppressed by adding a version
check.
* Use `std::iterator_traits` to extract `iterator_category`
In third-party STL implementations, `array_t::iterator` might be a pointer (e.g., `vector` in [EASTL](https://github.com/electronicarts/EASTL)) rather than a class, in which case directly using `array_t::iterator::iterator_category` is invalid. This commit fixes it with `std::iterator_traits`, which handles pointers correctly.

* Add key_compare member to ordered_map
* Replace == with key_compare in ordered_map
* Expose the actual comparison function used by object_t
nlohmann::ordered_map uses a different comparison function than the one
provided via template parameter.
* Introduce a type trait to detect if object_t has a key_compare member.
* Rename object_comparator_t to default_object_comparator_t.
* Add object_comparator_t to be conditionally defined as
object_t::key_compare, if available, or default_object_comparator_t
otherwise.
* Update the documentation accordingly.

* Add type traits to check if a type is usable as object key
Add type trait to check:
* if a type is a specialization of a template.
* if a type is a json_pointer.
* if a type is a basic_json::{const_,}iterator.
* if two types are comparable using a given comparison functor.
* if a type is comparable to basic_json::object_t::key_type.
* if a type has a member type is_transparent.
* if a type is usable as object key.
* if a type has an erase() function accepting a given KeyType.

* Rework basic_json element access to accept more key types
Rework basic_json element access member functions and operators to
accept any type that meets the requirements defined by type trait
detail::is_usable_as_key_type.
Member functions and operators:
* at()
* operator[]
* value()
* erase()
* find()
* count()
* contains()
Update documentation to reflect these changes.
Add unit tests to excercise the new functions using std::string_view.

AppVeyor build VMs should provide at least two cores. Parallelize builds
and tests.
In addition, enable output on failure and disable verbose test output.
Restore the previously disabled check for regression #3070 on all
compilers but MSVC.
To summarize the issue:
Given namespace fs = std::filesystem.
On MSVC attempting to construct an fs::path from json results in an
ambiguous overload resolution because fs::path can be constructed from
both a std::string as well as another fs::path.
To the best of my knowledge there is no way to fix an ambiguous overload
situation involving a type we do not control and with json implicitly
converting to both std::string and fs::path.
Re-enabling the check where it compiles and keeping it disabled for MSVC
is the best we can do.
Closes#3377 and #3382.
* Avoid clash with Arduino defines
* Arduino defines B0/B1 in "binary.h"
#define B0 0
#define B1 1
This clashes with names of the template
variables in conjuction
* Renaming them to "B" rather than "B1"
Now it can be used as-is in Arduino projects
* Apply suggestions from code review
