Convert export to default export

[c43721]

Reason for this change is because of the following:

import Rcon from 'rcon-srcds';

// Results in TypeError: rcon_srcds_1.default is not a constructor

However, if we use the alternative syntax to import everything as a constant:

import * as Rcon from 'rcon-srcds';

// Results in This module can only be referenced with ECMAScript imports/exports by turning on the 'esModuleInterop' flag and referencing its default export.

Changes:

// Old
export = RCON

// New
export default RCON

With the default export, everything works as expected.

Default export in an ECMAScript2017+ context makes sense. This module was originally written in 2018 in plain JS, and export = RCON was the normal convention 🤷‍♂️.

This is a very welcome change. Thanks, @c43721.

Awesome! I'll change over my backend to use this package now.
