Auto-insert FORGET statements

consider the program

EVERY 20 TICKS DO
  INPUT gas:: *sulfur* FROM me
  OUTPUT gas:: *sulfur* TO device EAST SIDE
  
  INPUT gas:: *oxygen* FROM me
  OUTPUT gas:: *oxygen* TO device WEST SIDE
END

when outputting the gas:: *oxygen*, this is seeing the input statement for sulfur. We can crawl the registry at program build to determine if there's any overlap, and if not, then we could automatically insert a FORGET, transforming the program into

EVERY 20 TICKS DO
  INPUT gas:: *sulfur* FROM me
  OUTPUT gas:: *sulfur* TO device EAST SIDE
FORGET
  INPUT gas:: *oxygen* FROM me
  OUTPUT gas:: *oxygen* TO device WEST SIDE
END

which would reduce wasted work trying to insert sulfur into a limitedslot filtering for only oxygen.

Because FORGET statements are fine-grained, this could get quite silly in complexity if we want to go all the way

EVERY 20 TICKS DO
  INPUT gas:: *sulfur* FROM me
  INPUT gas:: *oxygen* FROM bruh
  OUTPUT gas:: *sulfur* TO device EAST SIDE
FORGET me -- this could be auto-inserted, keeping the bruh input around
  INPUT gas:: *oxygen* FROM me
  OUTPUT gas:: *oxygen* TO device WEST SIDE
END

Probably should be a linter / clippy rule rather than something that happens behind the scenes
