I rewrote some of the python code to read avro files. I was able to
achieve a ~3x speedup over the current impl, and can probably do better if
it was cleaned up more. The main changes are:
* Eliminated the object-oriented nature of the reader. It's just functions
now. Presumably this can be changed back, but it didn't really seem like
there was any reason for it.
* Given a reader and writer schema, it precomputes as much helpful info as
it can upfront and caches this in a dictionary that the read functions use
* The code is compiled with Cython for speedup.
How can this be used to improve the current python api? Let me know how I
can be helpful...
