MemoEncoder.findMemo is Very Slow about dbase.net

This is what I love about open source development. I had not had a use case with a 200MB DBF before, so I didn't have any data about decoding speed. Thank you for finding this, and for submitting this code. I have committed it.

It is interesting to see that these LINQ methods are orders of magnitude slower than simple array indexing. You might expect them to be slightly slower due to overhead and a generic approach, but this much? Anyway, much better now.

I think there are other uses of LINQ methods in the source. I'll have to go through it to root them out.
