[BEAM-422] AvroSource: use a 64K buffer size for Snappy codec
commons-compress defaults to a 32K buffer size for Snappy.
However, Avro uses xerial.snappy to write, which has a 64K buffer size.
When the buffer size is too small, decoding data from Snappy can cause
an EOF exception rather than finishing data.
This fixes BEAM-422.
