Breaking change for file uploads.
Instead of a `data` dict containing all formdata,
a `files` dict is in the following endpoints
- emoji
- `create_custom_emoji()` takes `emoji_name` additionally to a `files` dict
- files
- `upload_file()` takes `channel_id` additionally to a `files` dict
- brand
- `upload_brand_image()`
- saml
- `upload_idp_certificate()`
- `upload_public_certificate()`
- `upload_private_key()`
- system
- `upload_license_file()`
- users
- `set_user_profile_image()`
See the documentation for an example.
