Copyright missing from MIT license file

[Teemu Vainio]

Hi,

I just noticed that there's no copyright defined in the LICENSE file. According to https://opensource.org/licenses/MIT template there should be a line that defines the copyright, something like: Copyright 2019 Viktor Hubert <[e-mail]>

Please add it to make the license file valid. Thanks!

Good catch, will release in v5 👌
