Unexpected output from binary when input includes tabs

[JarredAllen]

Whenever the input contains a tab character, it breaks the formatting of the text bubble (at least with the binary, I haven't tried the library).

For example, this is what I observe if it gets \thello, world as input:

$ printf '\thello, world' | fsays
 ______________
<       hello, world >
 --------------
        \
         \
            _~^~^~_
        \) /  o o  \ (/
          '_   -   _'
          / '-----' \

I would expect the output to look more like this (with the text matching the bubble in size):

$ printf '\thello, world' | fsays
 __________________
<     hello, world >
 ------------------
        \
         \
            _~^~^~_
        \) /  o o  \ (/
          '_   -   _'
          / '-----' \

I hit this issue because in my .bashrc I have the command fortune | cowsay, and I tried replacing cowsay with this crate, but fortune puts an output with tabs, which causes the output of fortune | fsays to be misformatted.
