COBRA options schema are listed as strings when they should be ints

[harper357]

Description of the bug

Trying to run COBRA and it requires three params, --cobra_assembler, --cobra_mink, --cobra_maxk. Currently the mink and maxk are expected to be strings, but they should be ints.

Related, cobra_assembler can only be "idba", "metaspades", or "megahit" per its documentation.

Made a quick draft PR #124 for this.

I haven't yet been able to test the test_cobra.config yet.
