Thanks to @pierre-dejoue for reporting and fixing issues.

Fixed

• an issue in read_pbm_binary when image width is a multiple of 8 (@pierre-dejoue)
• added missing include file (@pierre-dejoue)
• use binary mode while reading/writing a binary file (@pierre-dejoue)

Changed

• Host gitbook on app.gitbook.com instead of github pages with gitbook-cli because gitbook-cli is deprecated.

The first release.
