VIC-II: emit code to set raster irq

This function outputs assembly code needed to initialize a raster routine. In other words, asynchronously and in parallel with the execution of the main program, the routine starting from the label provided will be executed when the vertical brush on the screen reaches the value of _position. This function is particularly useful when the position is communicated is given as an integer.

Parameters

_environment	Current calling environment
_label	Label to jump to when vertical raster reach the value given
_positionlo	The vertical position to wait for (bits 7..0)
_positionhi	The vertical position to wait for (bit 8)
