Multiple eslint errors with salesforce's LWC eslint config

[thesunlover]

There are multiple 'for-in's that trigger eslint errors for the built version of the library: 119:4 error The body of a for-in should be wrapped in an if statement to filter unwanted properties from the prototype guard-for-in 162:4 error The body of a for-in should be wrapped in an if statement to filter unwanted properties from the prototype guard-for-in replacing Object.keys(def).forEach(()=>{}) is going to iterate only on the actual properties on the 'def' object.
