Usage of nested declare causes issues in Typescript

[mboughaba]

Dear,

When importing the lib in typescript: import { encode as windows1257Encode } from 'windows-1257

We get error below:

TS1038: A 'declare' modifier cannot be used in an already ambient context.

This is because we've got nested declare

declare module 'windows-1257' {
    // [...]
 
  export declare function encode(
    text: string,
    options?: EncodeOptions
  ): Uint16Array;
  
  // [...]
}

This prevents from using the library in Typescript
