Sets the match finder type.
<p>
Match finder has a major effect on compression speed, memory usage,
and compression ratio. Usually Hash Chain match finders are faster
than Binary Tree match finders. The default depends on the preset:
0-3 use <code>MF_HC4</code> and 4-9 use <code>MF_BT4</code>.

@throws      UnsupportedOptionsException
<code>mf</code> is not supported
