match satisfies behaviour of semvar

[Ankcorn]

Evaluating these conditions as false which the semvar library is evaluating to true

satisfies('3.0.3', '3.*')
satisfies('3.0.3', '3')

I believe this is because no operator is supplied so they are being compared with the = operator when "~" or "^" would match the behaviour I need.
