Use v0.4 display-interface

Hi! Thank you for helping out with SSD1306 development! Please:

[ ] Check that you've added documentation to any new methods
[ ] Rebase from master if you're not already up to date
[ ] Add or modify an example if there are changes to the public API
[ ] Add a CHANGELOG.md entry in the Unreleased section under the appropriate heading (Added, Fixed, Changed, etc)
[ ] Run rustfmt on the project with cargo fmt --all - CI will not pass without this step
[ ] Check that your branch is up to date with master and that CI is passing once the PR is opened
