Reliably identify runners between MOP and XML exports.

[otahirs]

As an organizer I want to upload results via MOP (Online Results service) or upload them manually later via IOF XML export.
However, today there is no shared identifier for the runners between these two export formats, which can create issues. We need to rely on some heuristic matching for the runners, which is never 100 % accurate, so today I have to discourage users to mix uploads from different sources.

Example, I use MOP during the event, after the race I do some more edits (e.g. DISQ runner), this time I export the results manually as XML and upload them to OResults.

For reliable matching between the two exports a common Id for the runners would fix the problem.

<cmp id="10001" card="8162875">
<base org="34976" cls="209408" stat="1" st="378600" rt="14050" crs="5">Otakar Hirs</base>
<input it="0" tstat="1"/>
</cmp>

I suggest adding meos id to the xml exports

<Person>
  <Id type="MEOS">10001</Id>
  <Id type="CZE">ZBM9801</Id>
  <Name>
    <Family>Otakar</Family>
    <Given>Hirs</Given>
  </Name>
</Person>
