IBM5150 - size property

[ArcadeShadow]

In some games the size property in the Floppy tag isn't the same of the size property in the Rom tag.
There are 2 games, like this ("centiped", "mspacman"). Is it normal or not?
As you can see below:

<software name="centiped">
	<description>Centipede</description>
	<year>1983</year>
	<publisher>Atarisoft</publisher>
	<info name="usage" value="PC Booter" />
	<part name="flop1" interface="floppy_5_25">
		<dataarea name="flop" **size="1049469"**>
			<rom name="centipede.mfm" **size="1011265"** crc="29332053" sha1="d34519a6cd21ac50ada1d78b28be138e77128635"/>
		</dataarea>
	</part>
</software>

This is just me being lazy with copy-pasting stuff, it should be the same. I have submitted a PR to fix it.
