Full Changelog: 0.3.2...0.4.0

• raw_bytes method on ImageData and BinaryTableData to access the raw bytes slice &[u8] (for cursor wrapped readers)

#25 - Fix bin table parsing bugs, especially occuring when selecting fields to parse
#24 - Ease the use allowing the user to access header even after getting the data

0.3.0

Features:

• Provide an iterator over the HDU list
• #16: Parsing of comments, history, continued, card as enum.
• #20 Basic support of Bintable
• #20 Faster parsing using the benefit of the Seek trait to skip data block not wanted
• Seek to a specific pixel in the ImageData struct
• Possibility to access the raw bytes of a binary table for cursor typed readers
• Fits is cloneable as long as the provided reader is cloneable
• #20 Tiled image convention for storing compressed images in FITS binary tables
  • Compression supported, GZIP, GZIP2 and RICE on u8, i16, i32 and f32. H_compress and PLI0 are not supported
  • Dithering techniques for floating point texture not well tested (test samples are welcome)
  • NULL_PIXEL_MASK column and ZMASKCMP keyword is not supported

Breaking changes:

• The iterator over HDUs is more rust idiomatic but introduces a different usage of the API
• Header.get method now takes a &str instead of a [u8; 8] slice.

Bugfixes:

• Be more safe about UB [https://github.com//issues/5]. BITPIX > 8 needs to be read from BigEndian scheme. It is thus necessary to create a new owned vector from the reading bytes. For BITPIX = 8, data can be directly read from the memory without allocating anything.
