feat: more flexible binds

[adriangb]

It might be nice to have more flexible binds, for example the option to:

• Bind by parameter name
• Bind by type
• Bind based on some other marker

This would probably require having a protocol like:

class BindMatcher(Protocol):
    def match(self, param: inspect.Parameter) -> Optional[DependantBase]:
        ...

The risk is that this increases complexity for non-existent use cases. This will probably not get implemented until it is requested by users.

Implemented!
