Function type notation error in types.d.ts

When launching our application with the latest code, we receive the following error.

Error: node_modules/read-excel-file/types.d.ts:19:37 - error TS1385: Function type notation must be parenthesized when used in a union type.

It looks like this line type SchemaEntryRequired = boolean | (row: Row) => boolean; needs to be changed to type SchemaEntryRequired = boolean | ((row: Row) => boolean);

I'm reverting to previous version for now, but wanted to let you know what we found. Thanks!
