New features:
 - Added a dedicated `Directory` type (#277)
 - Expose methods related to `Directory` publicly (#278)
 - Implement writing directories (#281, #283)
 - Add ICC (color profile) to the set of known tags (#287)
 - Added `Decoder.inner()` to access the underlying reader (#289)
 - Added methods for reading into a pre-allocated byte buffer (#285)

Changes:
 - No longer perform color conversion when decoding embedded JPEG. This fixes decoding for JPEG images with alpha channel. (#274)
 - More lenient LZW decoding to match libtiff (#231)

Fixes:
 - Fixed seeking multiple times in a row (#279)

This republishes 0.10.1, fixing an accidentally removed method (`Decoder::find_tag_unsigned_vec`).
