Ingvar Stepanyan b7e8f210d1 Remove InflateError 
It was left in but marked as deprecated as part of #132 to avoid breaking API changes.

However, #130 is going to mark a 0.7.0 release, so we can remove it altogether for simplicity.

Jonathan Behrens e70121efbb Merge pull request #132 from RReverser/deflate-improvements 
Improve deflate support
 2021-05-14 17:58:11 -04:00
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.
