Define a PL_infix_plugin hook, of a similar style to PL_keyword_plugin
Runs for identifier-named custom infix operators and sequences of
non-identifier symbol characters.
Defines multiple precedence levels for custom infix operators that fit
alongside exponentiation, multiplication, addition, or relational
comparision operators, as well as a "high" and "low" at either end.
