Andreas Molzer 1f7b25ef55 Fix read in packbits decoder 
This assumed that a `read` would succeed for the full length, thus
interpreting in a subsequent call some data bits as a header.

For instance, consider 77 bytes of literal were left and a buffer of
1024 bytes was provided. Then the `read` call might return 60 which was
ignored and assumed to be 77. Thus the next 17 bytes of literal data
were instead interpreted as a header due to setting `self.count` to 0.

Ingvar Stepanyan a6fb855121 Improve deflate support 
- Switch to streaming decompression via `flate2`. Aside from performance improvements and lower RAM consumption, this fixes a bug where `max_uncompressed_length` was precalculated for a single tile but then used as a hard limit on the whole data, failing to decompress any tiled images.
 - Deprecate `InflateError` - this was used for wrapping `miniz_oxide` raw status, but `flate2` already reports them as `io::Error` instead. This makes errors from both Lzw and Deflate modes more consistent - they're all now just `io::Error`.
 - Add support for new `Deflate` tag in addition to `OldDeflate` - format-wise it's same Zlib, and on practice decodes successfully with the same underlying code.
 - Slightly simplify partial reads from the `Reader` by using the `std::io::copy` helper instead of doing it manually.

Fixes #131.

Andreas Molzer 4d8c64bf1e Fix lzw decoding stopping short of full decode 
When the required amount of data was just a tiny bit larger than full a
page size (one buffer increment), the decoder would stop since all
compressed data had been read. However, the lzw decoder contains a small
internal bit buffer for code decoding. That is, some remaining bytes had
been retained and were still left to be decoded.
