Dbal 4 support ?

[signmeuptwice]

composer require boldtrn/jsonb-bundle

Problem 1
    - Root composer.json requires boldtrn/jsonb-bundle * -> satisfiable by boldtrn/jsonb-bundle[v1.0.0, v1.1.0, v1.2.0].
    - boldtrn/jsonb-bundle[v1.0.0, ..., v1.2.0] require doctrine/dbal ~2.4 -> found doctrine/dbal[v2.4.0, ..., 2.13.9] but the package is fixed to 4.0.4 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
