Large floats not accepted anymore

Describe the bug Version 1.9.2 no longer accepts 1+e9999 (or 2e+308 and anything above), regardless of allowSpecialFloats setting.

To Reproduce Steps to reproduce the behavior:

#include <iostream>
#include <json/json.h>
#include <sstream>

int main(int argc, const char* argv[])
{
    Json::CharReaderBuilder reader;
    reader["allowSpecialFloats"] = true;  // Makes no difference

    std::string s = "1e+9999";
    Json::Value val;
    std::string errors;
    std::stringstream json(s);
    if (Json::parseFromStream(reader, json, &val, &errors)) {
        std::cout << s << " -> " << val.asDouble() << "\n";
    } else {
        std::cout << errors;
    }
    return 0;
}

Expected behavior

• 1e+9999 -> inf

Actual behavior:

* Line 1, Column 1
  '1e+9999' is not a number.

Desktop (please complete the following information):

• OS: Fedora 34
• Meson version 0.59.1
• Ninja version 1.10.2

Additional context

• Version 1.9.1 accepts value 1e+9999 as infinite, regardless of allowSpecialFloats setting.
• Version 1.9.2 no longer accepts 2e+308 or above, regardless of allowSpecialFloats setting.

Specifically breaking change seems to be commit 645cd0412c "Number fixes (#1053)".
