Row format better data packing #2337

Feature Request

I have been working to convert an application from Fory serialization format to use Row Format for better compatibility and hopefully less space usage (since each row does not have to save information about the data structure)

However, the savings are not as much as I would have liked. I think part of the problem is that the row format seems to be quite wasteful in the fixed fields area - all fields are aligned to 8 bytes, even boolean or short, so there is a lot of zero-padding, based on the BinaryRowWriter implementation.

Is this necessary? Or would it be possible that we can improve the row format to have less padding, when fields are known to have smaller sizes?
