Added a Cheat Sheet to help users get the most out of the logging library

Removed ArgSizeCalculator<>, Encoder<>, and Decoder<> classes. These have been consolidated into a single Codec class. Users who wish to pass user-defined objects should now specialize this single Codec class instead of managing three separate classes. For guidance, please refer to the updated advanced example

Added TriviallyCopyableCodec.h to facilitate serialization for trivially copyable user-defined types. For example

  struct TCStruct
  {
    int a;
    double b;
    char c[12];

    friend std::ostream& operator<<(std::ostream& os, TCStruct const& arg)
    {
      os << "a: " << arg.a << ", b: " << arg.b << ", c: " << arg.c;
      return os;
    }
  };

  template <>
  struct fmtquill::formatter<TCStruct> : fmtquill::ostream_formatter
  {
  };

  template <>
  struct quill::Codec<TCStruct> : quill::TriviallyCopyableTypeCodec<TCStruct>
  {
  };

  int main()
  {
    // init code ...

    TCStruct tc;
    tc.a = 123;
    tc.b = 321;
    tc.c[0] = '\0';
    LOG_INFO(logger, "{}", tc);
  }

Added support for passing arithmetic or enum c style arrays when std/Array.h is included. For example

  #include "quill/std/Array.h"

  int a[6] = {123, 456};
  LOG_INFO(logger, "a {}", a);

Added support for void const* formatting. For example

    int a = 123;
    int* b = &a;
    LOG_INFO(logger, "{}", fmt::ptr(b));

Added support for formatting std::chrono::time_point and std::chrono::duration with the inclusion of quill/std/Chrono.h

#include "quill/std/Chrono.h"

std::chrono::system_clock::time_point now = std::chrono::system_clock::now();
LOG_INFO(logger, "time is {}", now);

Removed unused method from ConsoleSink
