Remove WebcamDefaultDriver from core webcam-capture module.

[msgilligan]

The core webcam-capture module on the current master branch uses the WebcamDefaultDriver class by default. This is undesirable for several reasons:

1. The bundled IMAJ binaries increase the JAR size and are a maintenance issue.
2. The dependency on BridJ is obsolete and even if updated will be a maintenance issue.
3. The dependency on BridJ is currently causing failures on macOS. There are newer image capture drivers that do not require or use Bride.

I propose we remove the WebcamDefaultDriver and related classes, the BridJ dependency, and the bundled binary libraries from the core JAR. Perhaps an "uber" or "-all" JAR can be added to the project as an alternative or maybe just improve/double-check the documentation of the process of how to use the IMAJ driver.
