inspec2xccdf errors when cci tag is not an array

[rlakey]

Scenario
A profile created with csv2inspec does not create the cci tag as an array so then taking the same profile and using inspec2xccdf results in the following errors:

A profile created from xccdf2inspec does have the cci tag as an array when using an officially published STIG xccdf file.

This was just fixed with #241 by performing type checking on the CCI field before it gets written to inspec.
