README markdown parsing issues

[jwoertink]

This may be a bit out of scope, but I just noticed that with the docs for Breeze, the README doesn't display normally

Feel free to close if this isn't relevant 😄

Markd, the markdown parser / html generator that crystal uses for documentation, didn't get table support until recently. The markd dependency in the crystal repo needs to be updated and a new release should happen, then this should be fixed
