In NettyByteBuf, we currently call order(LITTLE_ENDIAN) on a Netty ByteBuf, which wraps the original Big Endian buffer in a SwappedByteBuf. On little-endian platforms, this causes a double byte reversal:

• First, we read the buffer in LE, reversing bytes to BE

• Then, the SwappedByteBuf reverses them again to simulate LE

This results in unnecessary overhead.

In addition, Netty’s javadoc documentation on order() method advises:

Use the Little Endian accessors (e.g., getShortLE, getIntLE) instead of creating a buffer with swapped endianness via order().

We should:

• Remove the call to order(LITTLE_ENDIAN)
• Internally track endianness via a boolean (e.g., isLittleEndian)

Based on this flag, use the appropriate Netty accessor methods:

• getLongLE, getIntLE, etc. for LE
• getLong, getInt, etc. for BE

This avoids the creation of an intermediate SwappedByteBuf and prevents redundant byte reversal logic.
