Broken compability with newer versions of css_inline library

[ididit4you]

Hi @FelixSchwarz!
There was broken changes in css_inline after v0.9.0 interface was changed and now it does not allow inline_style_tags attribute.

Last working v0.9.0
New v0.10.0

Possible solutions:

1. Set fixed version in setup.cfg to the v0.9.0
2. Support the new css_inline.CSSInliner interface end test how it works

Thank you for the report. I'll look into that. I think this was also brought up in #42. Should be a big thing to handle (ideally old + new API ?).

Unfortunately the inline_style_tags option was removed without an obvious replacement so for now I released mjml-python v0.9.1 which pins the dependency to the old version.

I just noticed that @caseyjhol already filed an issue upstream and the upstream author agreed to reinstante the parameter.

I'm working on a PR that will pin the css-inline version (but I've been waiting for the latest version with the fix to come out first). I've also discovered another CSS issue related to child selectors that I'll be pushing up a fix for.

If we want to pin to an old version, we'll need to pin to 0.8.7 as 0.9.0 has been yanked.

FYI, I am working on a PR that re-introduces the inline_style_tags option with the same behavior as before.

The inline_style_tags option is reintroduced in css-inline==0.11.0
