Changes

• Remove ARDUINOJSON_EMBEDDED_MODE and assume we run on an embedded platform.
  Dependent settings (like ARDUINOJSON_DEFAULT_NESTING_LIMIT) must be set individually.
• Change the default of ARDUINOJSON_USE_DOUBLE to 1
• Change the default of ARDUINOJSON_USE_LONG_LONG to 1 on 32-bit platforms
• Add as<JsonString>() and is<JsonString>()
• Add safe bool idiom in JsonString
• Add support for NUL in string values (issue #1646)
• Add support for arbitrary array rank in copyArray()
• Add support for char[][] in copyArray()
• Remove DeserializationError == bool and DeserializationError != bool
• Renamed undocumented function isUndefined() to isUnbound()
• Fix JsonVariant::memoryUsage() for raw strings
• Fix call of overloaded 'swap(BasicJsonDocument&, BasicJsonDocument&)' is ambiguous (issue #1678)
• Fix inconsistent pool capacity between BasicJsonDocument's copy and move constructors
• Fix inconsistent pool capacity between BasicJsonDocument's copy and move assignments
• Fix return type of StaticJsonDocument::operator=
• Avoid pool reallocation in BasicJsonDocument's copy assignment if capacity is the same
• Avoid including Arduino.h when all its features are disabled (issue #1692, PR #1693 by @paulocsanz)
• Assume PROGMEM is available as soon as ARDUINO is defined (consequence of #1693)
