test(wildcard): Updated Wildcard Tests to include V0 (#7)

* fix(wildcard): Wildcards allowing nonexistant VPin 33

Commit 4bd673b causes read/write wildcard tests to fail, as it allows a nonexistant virtual pin 33 t
o be passed to a wildcard decorator.

* fix: Reverted Code Change, Updated Tests

Mistake on my part, not sure what I was thinking there.
