Make error buffer optional

[MichaelXavier]

Hi! I've been using and enjoying dhall-mode but I was wondering if it would be possible to add an option that when toggled on would suppress the dhall error buffer. It replaces one of the existing buffers if you have multiple buffers per window and it can be kind of disruptive to your workflow. In the mean time I'm planning on wrangling the buffer with popwin so that it always creates a new buffer that can be easily dismissed, e.g. ("*dhall errors*" :height 10 :noselect t :stick t :tail nil)
