🔨 approach to un-break the changes for #462

💥 CBOR/MessagePack input must end with EOF #505
...
The CBOR and MessagePack parsers now expect the input to be read until the end. Unless the new parameter "strict" is set to false (it is true by default), an exception is raised if the parser ends prematurely. This is a breaking change as the parsers ignored unread input so far.
Furthermore, the offset/startIndex paramter introduced in #462 was removed as this behavior can be mimicked with an iterator range. For instance, instead of calling "from_cbor(vec, 5);", you can write "from_cbor({vec.begin()+5, vec.end()});".

You can now pass a boolean "allow_exceptions" to the parse functions. If it is false, no exceptions are thrown in case of a parse error. Instead, parsing is stopped at the first error and a JSON value of type "discarded" (check with is_discarded()) is returned.

🔨 using input/output adapters for CBOR and MessagePack

- You can now pass a reference to a vector to the to_cbor and to_msgpack functions. The output will be written (appended) to the vector. #476
- You can now pass an output stream with uint8_t character type to the to_cbor and to_msgpack functions. #477
- You can now read from uint8_t */size in the to_cbor and to_msgpack functions. An input adapter will be created from this pair, so you need to use braces. #478

🐛 fix for #656
...
A complete rewrite of the string escape function. It now provides codepoint-to-\uxxxx escaping. Invalid UTF-8 byte sequences are not escaped, but copied as-is. I haven’t spent much time optimizing the code - but the library now agrees with Python on every single Unicode character’s escaping (see file test/data/json_nlohmann_tests/all_unicode_ascii.json).
Other minor changes: replaced "size_t" by "std::size_t"

🚧 manual lexer
...
This commit removed the re2c lexer and replaced it by a manual version.
Its integration is not yet complete: number parsing does not respect
locales or overflows. Furthermore, parsing does not need to end with
EOF. Therefore, a lot of test cases fail. The idea is to push this
branch forward so we can conduct performance comparisons. So far, a
nice side effect are better diagnosis messages in case of parse errors.

🚑 added special case to fuzzers to fix #504
...
Since #329 , NaN and inf numbers do not yield an exception, but are
stored internally and are dumped as “null”. This commit adjusts the
fuzz testers to deal with this special case.

💥 implemented new handling of NaN and INF #70 #329 #388
...
- If an overflow occurs during parsing a number from a JSON text, an
exception (std::out_of_range for the moment, to be replaced by a
user-defined exception #244 ) is thrown so that the overflow is detected
early and roundtripping is guaranteed.
- NaN and INF floating-point values can be stored in a JSON value and
are not replaced by null. That is, the basic_json class behaves like
double in this regard (no exception occurs). However, NaN and INF are
serialized to “null”.
- Adjusted test cases appropriately.

🚑 fix for #493

Added a test to check if the input stream is good() before executing
getline on it. Also added two test cases that set the failbit and
badbit before calling file_line_buffer.

MSVC needs this overload to compile code containing a std::map that
uses nlohmann::detail::operator as key.

🚑 fix for #492
...
The original test case relied on an invalidated iterator. This error
did not occur before, but only with GCC with -D_GLIBCXX_DEBUG. This
commit fixes the test case. The library is unaffected by this change.
