- Previously: if the header field is not an attribute type, then
it was added as an attribute field.
PyMISP then used to skip it if needed
- Now: Those fields are discarded before they are put in an attribute
- If more than 1 misp type is recognized, for each one an
attribute is created
- Needs to have header set by user as parameters of the module atm
- Review needed to see the feasibility with fields that can create
confusion and be interpreted both as misp type or attribute field
(for instance comment is a misp type and an attribute field)
