Add version check in command line

[cameronmartino]

Add a version output, recommended by Devon O'rourke, in the command line implementation of DEICODE. See the following: https://forum.qiime2.org/t/when-things-look-good-i-wonder-where-ive-gone-wrong/10684

I think you should be able to just use @click.version_option() in https://github.com/biocore/DEICODE/blob/master/deicode/scripts/_standalone_rpca.py (importing the current version string from deicode.__init__) to do this.

...I should probably add this to Qurro also :)
