BitfieldDatatypeWriter class

Writer for bitfield HDF5 datatypes

This class handles writing datatype messages for bitfield types, which represent bit-level data storage. Bitfields are used for packed bit flags and other bit-oriented data.

The writer follows HDF5 datatype message format version 1 for bitfield class (4).

Example usage:

// Create an 8-bit bitfield
final writer = BitfieldDatatypeWriter(
  size: 1,
);

// Create a 32-bit bitfield
final writer2 = BitfieldDatatypeWriter(
  size: 4,
);

final message = writer.writeMessage();
