## Summary
Adds PERF101 which checks for unnecessary casts to `list` in for loops.
NOTE: Is not fully equal to its upstream implementation as this
implementation does not flag based on type annotations
(i.e.):
```python
def foo(x: List[str]):
for y in list(x):
...
```
With the current set-up it's quite hard to get the annotation from a
function arg from its binding. Problem is best considered broader than
this implementation.
## Test Plan
Added fixture.
