Breaking changes

• Changed number traits used by JsonWriter methods number_value and fp_number_value
  This most likely only affects custom JsonWriter implementations. See below for details.

Changes

• Fixed JsonStreamReader::next_name sometimes returning wrong results (#10)
• Added StringValueWriter::write_str
• Tried to improve number reading and number string writing performance
• Tried to improve JsonStreamReader::transfer_to performance for string values
• Adjusted number traits used by JsonWriter methods number_value and fp_number_value
  These changes are mainly relevant for custom implementations of JsonWriter.
  • IntegralNumber has been renamed to FiniteNumber to better describe its behavior
  • Number traits no longer have ToString and Copy as supertraits; instead they have a new use_json_number method to consume a str
  • Number traits have new methods to obtain the value as u64 / i64, respectively f64
