Consider how to expose optional deps for plugins

[TimMonko]

🧰 Task

Currently, many image formats are purpoted to be read by something like imageio but requires backend optionals, (i.e. imageio[fits]). This can probably be done by changing the BIOIO_PLUGINS dict to include a representation of the library[optional] for the plugin installer. This in the end means we could make bespoke ndevio optionals like ndevio[imageio-all] to pull in specific optionals and do dep pinning if necessary.
There is also imageio[tifffile] and I wonder if that would perform the same duty as bioio-tifffile effectively for bioio-imageio, that would be great and cause less environment mixing, I think.
