add tool configuration via pyproject.toml

[CagtayFabry]

Some configuration options would be nice, on the top of my head:

• list of dependencies to install via pip
• mapping of dependency names that differ for pip and conda (e.g. weldx-widgets -> weldx_widgets)

The pip list can also be provided by the env.yaml, right? So we would just require another loop for it and redirect the package names to pip.
This step has to occur after the mapping of the package names of course.

Another useful option could be to override the name of the environment. Also channels could be overridden by the config IMO.

exactly the packages should just be placed in the pip section of the environment

yes setting default config values in a config file sounds good

Actually this issue is the blocker to install (new) environments during testing in the weldx repository.
