Change class name UclaMiniscopeV4CameraFrame -> UclaMiniscopeV4CameraDataFrame

[cjsha]

This name change suggestion is to adhere to our naming convention. The operator is UclaMiniscopeV4CameraData so its corresponding frame should be appended by "Frame": UclaMiniscopeV4CameraDataFrame.

There apparently was a discussion about why this particular operator had a different name.
If this is the case, we should at least document in the code the rationale for not adhering to the convention.

The rational, maybe flawed, was that it is common for people to talk about "Camera Frames" when they are they are thinking about some matrix of values that forms a picture. Camera Data Frames sounds clunky in comparison. In other cases, there is no common phrase -- e.g. people don't have a preconceived idea about what a Neuropixels Frame is.

@jonnew @cjsha the only counter argument I can see is that a "camera frame" is usually understood as something which is itself an image (i.e. which can be plotted directly), whereas in this case, this object is not by itself an image, but instead contains an "Image" field (among other metadata) which is what is used for saving and visualisation.

The above rationale is also why in other Bonsai camera packages we use the suffix "DataFrame" rather than "Frame", so this change could also be potentially more recognisable by the community (although this of course is definitely more of a subjective assessment).
