Lewton enters an apparently infinite loop on decoding this file: lewton-infinite-loop.ogg.zip

Steps to reproduce:
RUSTFLAGS='--cfg=fuzzing' cargo run --release --example perf /path/to/file.ogg

Tested on commit 9078060. Found with AFL.rs

Address issue #46
adb2d6e 
The infinite loop is caused by classwords_per_codeword
being zero, which makes partition_count never increase
so the while partition_count < partitions_to_read loop
never terminates.
