### Summary

Add support for HiDrive without using WebDAV.

### Motivation

Copied from [cryptomator/ios#264:](https://github.com/cryptomator/ios/issues/264)
> Currently, it's already possible to use HiDrive via WebDAV. However, is comes with two caveats:
>
> 1. You have to pay for the HiDrive protocol package.
> 2. You have to deactivate 2FA to use WebDAV comfortable.

> Using the [HiDrive API](https://developer.hidrive.com/) would be more convenient.
