Invalid `GOTOPOINTS` allowed.

[python-processing-unit]

According to the specification section 3.7:

GOTOPOINT(n) MUST register a jump target identified by the runtime value n, where n MAY be either INT or STR. Negative integer gotopoint identifiers are invalid.

The implementation, however, allows GOTOPOINTs of any type, and allows negative INT GOTOPOINTs.

Prefix REPL. Enter statements, blank line to run buffer.
>>> GOTOPOINT(<>)
>>> GOTOPOINT([0b1])
>>> GOTOPOINT(LAMBDA INT: (){})
>>> GOTOPOINT(ASYNC{})
>>> GOTOPOINT(0b1.0)
>>> GOTOPOINT(-0b1)
