Updating single header, prior to release.

New release candidate (#1856 )
* Patch for possible AVX-512 overflow. * Updating the test for new padding. * Preparing new version. * replace binary integer literals with hex literals for C++11 compatibility (#1855) Binary integer literals are a C++14 feature, so those are not supported in C++11 and should be replaced by hexadecimal literals instead. Fixes #1854. Co-authored-by: Dirk Stolle <striezel-dev@web.de>

Example for such a commit: `[skip ci] Fixed typo in power_of_ten's docs`
   This benefits the project in such a way that the CI pipeline is not burdened by running jobs on changes that don't change any behavior in the code, which reduces wait times for other Pull Requests that do change behavior and require testing.

+Raw Strings
+-----------
+
+It is sometimes useful to have access to a raw (unescaped) string: we make available a
+minimalist `raw_json_string` data type which contains a pointer inside the string in the
+original document, right after the quote. It is accessible via `get_raw_json_string()` on a
+string instance and returned by the `key()` method on an object's field instance. It is always
+optional: replacing `get_raw_json_string()` with `get_string()` and `key()` by
+`unescaped_key()` returns an `string_view` instance of the unescaped string.
+
+You can quickly compare a `raw_json_string` instance with a target string. You may also
+unescape  the `raw_json_string` on your own string buffer: `parser.unescape(mystr, ptr)`
+advances the provided pointer `ptr` and returns a string_view instance on the newly serialized
+string upon success, otherwise it returns an error. When unescaping to your own string buffer,
+you should ensure that you have sufficient memory space: the total size of the strings plus
+`simdjson::SIMDJSON_PADDING` bytes. The following example illustrates how we can unescape
+JSON string to a user-provided buffer:
+
+```C++
+    auto json = R"( {"name": "Jack The Ripper \u0033"} )"_padded;
+    // We create a buffer large enough to store all strings we need:
+    std::unique_ptr<uint8_t[]> buffer(new uint8_t[json.size() + simdjson::SIMDJSON_PADDING]);
+    uint8_t * ptr = buffer.get();
+    ondemand::parser parser;
+    ondemand::document doc = parser.iterate(json);
+    // We store our strings as 'string_view' instances in a vector:
+    std::vector<std::string_view> mystrings;
+    for (auto key_value : doc.get_object()) {
+      std::string_view keysv = parser.unescape(key_value.key(), ptr);// writes 'name'
+      mystrings.push_back(keysv);
+      std::string_view valuesv = parser.unescape(key_value.value().get_raw_json_string(), ptr);
+      // writes 'Jack The Ripper 3', escaping the \u0033
+      mystrings.push_back(valuesv);
+    }
+```

However, we only allow AVX-512 on recent processors (Ice Lake/Tiger Lake or better) where [little to no frequency throttling is expected](https://travisdowns.github.io/blog/2020/08/19/icl-avx512-freq.html). If you can still concerned, you can easily disable AVX-512 with the CMake option `SIMDJSON_AVX512_ALLOWED` set to `OFF` (e.g., `cmake -D SIMDJSON_AVX512_ALLOWED=OFF -B build && cmake --build build`) or by setting
+the macro `SIMDJSON_AVX512_ALLOWED` to `0` in C++ prior to importing the headers.

 You may still be worried about which SIMD instruction set is used by simdjson.  Thankfully,  [you can always determine and change which architecture-specific implementation is used](implementation-selection.md) by simdjson. Thus even if your CPU supports AVX2, you do not need to use AVX2. You are in control.
