Unnecessary forcing of allocation in some public APIs

Hey, and thanks for making this! I've seen that a bunch of public-facing APIs, such as the main entry point to text embeddings, [`TextEmbedding::embed()`](https://docs.rs/fastembed/latest/fastembed/struct.TextEmbedding.html#method.embed), and some utilities e.g. [`read_file_to_bytes()`](https://docs.rs/fastembed/latest/fastembed/fn.read_file_to_bytes.html) (btw,...
