No way to pass `pretrained=False` to `DINOv2Encoder`

[barwojcik]

Issue

There is no way to initialize the DINOv2Encoder with random weights. It's problematic because it forces the download even if weights are later loaded. I raised this issue in map anything repo: facebookresearch/map-anything#149

Proposed solution

Pass pretrained parameter here: https://github.com/castacks/UniCeption/blob/main/uniception/models/encoders/dinov2.py#L89
It seems straightforward, check if pretrained is in the kwargs and "pop" them before they are passed to base class. I can submit PR in a spare time if this propositions sounds ok for you.
