[WIP] Adapt to dry-view 1.0

[waiting-for-dev]

This can be used as starting point to adapt the project when dry-view 1.0 is released.

References AMHOL/roda-flow#5, which would also need a fix.

One option is also to add erbse to the Gemfile with a notice about it could be safely removed if erb format is not used with dry-view. However, dry-view warning is quite explicit in that case.

Hi @waiting-for-dev, Do you have any news about this PR, it helps me to fix some issues but i'm struggled with the render of the view?

I'm not sure it will get more attention because dry-web-roda will be abandoned in favor of hanami 2. That being said, dry-web-roda is not much more than a bunch of small libraries working together, so our code won't need too much change to still rely on actively developed libraries. You can ask me whatever you need in dry-rb discussion forums.

I guess this can be closed in favor of #94
