Lint for sum and product in consensus code (#2226) ## Issue Addressed Closes #1621 ## Proposed Changes Use the `disallowed_method` lint to ban uses of `Iterator::{sum,product}` from `types` and `state_processing`. ## Additional Info The lint is turned off in the tree hash caching code, as it is performance sensitive and overflowy arithmetic is already allowed there. 2021-03-01 00:57:13 +00:00			`# Disallow sum and product methods which are prone to overflow.`
