feat: Control Net support + Textual Inversion (embeddings) (#131)

* add controlnet to pipeline

* add cli params

* control strength cli param

* cli param keep controlnet in cpu

* add Textual Inversion

* add canny preprocessor

* refactor: change ggml_type_sizef to ggml_row_size

* process hint once time

* ignore the embedding name case
