Hyphens in metadata column names passed to ancombc's --p-formula being interpreted as formulaically meaningful #129

It seems that when a user specifies a metadata column name that contains hyphens, e.g. my-column to the --p-formula option to qiime composition ancombc, the hyphens are interpreted as mathematical symbols and one term becomes two: my and column. Then the metadata key errors on my. This is happening here.

See forum post here.

Hey @colinvwood just FYI there's already an open issue on this: https://github.com/qiime2/q2-composition/issues/100
