Do not use gzip, invalid byte sequence in UTF-8 (ArgumentError)

Hi. I'm using this gem in ruby 2.7.0. It gives this error:

irb(main):001:0> require 'textrazor'
=> true
irb(main):002:0> client = TextRazor::Client.new('...')
irb(main):003:0> client.analyse('Bill Gates is a co-founder of Microsoft')

Disabling gzip fixes this problem. Alternative solution can be to handle gzip response correctly.

Hey, thanks for the PR. Did this work for you before and broke in ruby 2.7? No one reported this before, so I wonder this could be a ruby 2.7 particular issue.

I haven't used this gem in ruby < 2.7, so I don't know.
