Options type declaration is missing underlying stream properties

[valeneiko]

Describe the bug

csv-parse and csv-stringify (possibly others too) have Options class defined, which does not extend corresponding Stream options.

To Reproduce

import * as csvParse from 'csv-parse';
const csvReader = csvParse({ highWaterMark: 65 * 1024 });

Will produce a type error, because highWaterMark is not defined on parse.Options, but if compiled (ignoring the error) the code works as expected.

Additional context The Options interface should extend DuplexOptions interface. But encoding property is defined in both and is not compatible, so may need to be omitted from one of the types.

The following d.ts definition file can be use as a workaround:

import { DuplexOptions } from 'stream';

declare module 'csv-stringify' {
    interface Options extends Omit<DuplexOptions, 'encoding'> {}
}

declare module 'csv-parse' {
    interface Options extends Omit<DuplexOptions, 'encoding'> {}
}
