Another new check is 'DuplicateConditions'. The name speaks for itself, `if` statement chains with duplicate conditions and expressions containing `and`/`or` operations with redundant parts will now be detected:
```lua
if x then
-- ...
elseif not x then
-- ...
elseif x̳ then -- Condition has already been checked on line 1
-- ...
end
local success = a and a̳ -- Condition has already been checked on column 17
local good = (a or b) or a̳ -- Condition has already been checked on column 15
```
We've also fixed an incorrect lint warning when `typeof` is used to check for `EnumItem`.
