Add torchgeo models

[paolofraccaro]

Added different models as implemented in torchgeo. Added a related test file and passing all other tests. Only issue is mmseg installation imcompatible with updated version of timm.

Is terratorch.datasets.sen1floods11_lat_lon.Sen1Floods11NonGeo going to replace terratorch.datasets.sen1floods11.Sen1Floods11NonGeo ? Or should we keep both ?

By running the automatic tests pytest -s tests/test_encoder_decoder_torchgeo_models.py::test_create_pixelwise_model_dofa, I see the error:
FAILED tests/test_encoder_decoder_torchgeo_models.py::test_create_pixelwise_model_dofa[True-IdentityDecoder-segmentation-expected1-dofa_large_patch16_224] - AttributeError: 'DOFA' object has no attribute 'embed_dim'
In fact, the dofa model here:
terratorch/models/backbones/dofa_vit.py:64: in init
self.out_channels = [self.dofa_model.embed_dim] * len(self.out_indices)
has no attribute called embed_dim.
I'm using timm==0.9.7 and Python 3.12.

Should we replace the current torchgeo version from requirements and pyproject.toml by:
torchgeo @ git+https://github.com/microsoft/torchgeo?
