Bug#883867: bookworm for accessibility

[hjenkins]

Packaging the Bookworm e-reader could significantly improve the 
accessibility of Debian. Bookworm is written by blind developers, 
according to its website.

E-book readers are important if you are vision-impaired. Many e-book 
programs don't work well with screenreaders. Bookworm has and interface 
and documentation that is accessible to the vision-impaired, and it also 
has good independent reviews from sighted users.

FBreader seems to have been proprietized (formerly GPL2 or later)! I'm 
not sure if it's been forked or what; there do not seem to be new 
updates.
