create implication competition_school_swimsuit -> school_swimsuit

Link to implication

As the name suggests. It's still regarded as a "school swimsuit" even in Japan (the "new" kind), just not like the "old" kind several of us commonly associate with this term.

There needs to be a way to find the images where both types of school swimsuits are pictured, but with some implications already in place (particularly the one from nontraditional_school_swimsuit), it seems well established that school_swimsuit is meant to be a particularly broad tag (and not focused on any specific type(s)). I think I will start an old_school_swimsuit tag to cover those instances.

-1. sukumizu is a pretty specific fetish and is distinct from competition school swimsuit.

The tag implication competition_school_swimsuit -> school_swimsuit has been rejected.
