Add emperor mchelper with CF data

In order to expedite PRs emperor mchelper should be added with the CF dataset (below). As suggested by @mortonjt in PR #38. May need the expertise of @ElDeveloper.

This should follow the commands:

```shell
# microbes
deicode --in-biom filtered_otus_nt.biom --output-dir deicode_microbes --n_components 3 --max_iterations 10
qiime tools import --input-path deicode_microbes/ordination.txt --output-path ordination.qza --type "PCoAResults % Properties('biplot')"
qiime emperor biplot --i-biplot ordination.qza --m-sample-metadata-file sample-metadata.txt --output-dir emperor-microbes
# metabolites
deicode --in-biom filtered_lcms_nt.biom --output-dir deicode_metabolites --n_components 3 --max_iterations 10
qiime tools import --input-path deicode_metabolites/ordination.txt --output-path ordination.qza --type "PCoAResults % Properties('biplot')"
qiime emperor biplot --i-biplot ordination.qza --m-sample-metadata-file sample-metadata.txt --output-dir emperor-metabolites
```

Generating something like the following for each PR:

#### microbes
#### metabolites
