Target ids include species info

[owlang]

Motivation: I want to add aliases to the targets that are sometimes species-specific. To avoid target ambiguity, the current targets could be separated into more specific targets. This may be useful for antibodies that were made against mouse/human type peptides but work across species.

Implementation 1 - Target id species defined by antibody target

Implementation 2 - Target id species defined by strain or biosample being processed

Concerns with this idea: this would increase complexity of Target info. There would also be challenges with backward-adding this information. A stop-gap could be to set all current targets to ambiguous species and include aliases across all species.
