Braille 6dot formats support

[sthibaul]

Hello,

Braille embossers may support only 6dots printing, so there is a need
for 6dot unicode braille and iso braille formats. The attached patch
adds .ubrl6 and .isobrl6 formats for that.

(Mmm, not the best way to submit a patch of course, but I couldn't find how to create an account on http://git.imagemagick.org/)

We have not opened account registration at our main server. You can use our mirror at github or gitlab to send us a pull request. It would make us happy if you use our code conventions and write 'cell_height = 3' as 'cell_height=3'

We can also integrate your patch manually if you don't want to use github or gitlab.

Your patch has been applied to our GIT repository. Thanks!
