Description

It's possible to restrict a function in all modules except certain modules:

- functions:
  - {name: [fromIntegral], within: 'modules_where_fromIntegral_is_ok'}

But it doesn't seem possible to restrict a function only in certain modules. This would be a useful feature to add.

Contributor guide

Research direction
Explore the hlint source code to understand how function restrictions with 'within' are currently implemented. Then modify the configuration parsing and restriction logic to support specifying a set of modules where the restriction applies, in addition to the existing 'except' behavior. Test the changes with examples.
