#22 Cat 10 Amplitude of Primary Plot field's msb should be 8

[Gabor Zavarko]

In the current xml it is 16, which is wrong. Should be 8:

    <dataitem id="I010/131" frn="24" format="fixed" length="1">
      <name>Amplitude of Primary Plot</name>
      <definition>Amplitude of Primary Plot</definition>
      <field octed="1" msb="**16**" lsb="1">
        <name>PAM</name>
        <format>uint</format>
        <desc>The value is radar-dependent, 0 being the minimum detectable level for that radar.</desc>
      </field>
    </dataitem>
