Feature Request

poetry add does not currently accept an option to set a marker, e.g.:

poetry add smbus2 --markers="platform_machine == 'armv7l'" ->

smbus2 = {version = "^0.3.0", markers = "platform_machine == 'armv7l'" }

This would be useful to add a dependency without having to write it in pyproject.toml manually and running poetry update, which may undesirably update other dependencies.
