Regression (only in git): some files fail to decode

[Shnatsel]

#39 seems to have caused a regression. Some PNGs now fail to decode with this error:

called Result::unwrap() on an Err value: Decoding(DecodingError { format: Exact(Png), underlying: Some(Format(FormatError { inner: CorruptFlateStream { err: InvalidUncompressedBlockLength } })) })

Here's a couple samples triggering the issue: fdeflate_decode_failures_67100397.zip

Tested with https://github.com/fintelia/corpus-bench

These files are from my web-scraped corpus which you can download and try locally yourself. It is 58,000 files but most of them are very small so decoding all of them only takes a few minutes.

Thanks for reporting! Seems it was a small oversight in not initializing the eof mask/length when using the precomputed tables
