* feature: DoRA adapter for Embeddings
* feature: wire in DoRAEmbedding
* bugfix: ensure self.m is recalculated when the linear layer is changed in DoRALinear.from_linear
* refactor: prefer from_base over from_linear or from_embedding. prefer fuse over to_linear or to_embedding
* cleanup: remove unused imports in test_dora.py
* refactor: remove unnecessary non_layer_modules
* cleanup: remove wrong comments for lora embedding dropout. remove uncessary parens in dora embedding dropout
