Added

• Add a note in documentation to usage and api about the need of sorted object dictionary
• Add support for SDO client segmented transfers @tonbo777
• Add support of mapping values with 3 bytes in PDOs
• Introducte callbacks for read/write PDO mapped values larger than 4 bytes

Changed

• Adjust SDO client API documentation to reflect conditions for expedited and segmented transfers

Fixed

• Avoid variable declaration if SDO client is disabled @jernejsk
• Allow direct data in object dictionaries running on 16bit microcontrollers

Note: The datatype in the object dictionary was uintptr_t in previous versions. For 16bit microcontrollers uintptr_t may contain only 24bit instead of the required 32bits for direct data storage. For this reason, in version 4.3.0 and later the object dictionary should use CO_DATA as data type.
