AsyncFileField widget

[davecoates]

Currently no generic widget for new UI library, so it's currently BYO

We need to add the to @alliancesoftware/ui and then update our implementation here to include it by default / add the alliance_platform/storage/widgets/async_file_input.html template (currently it uses this template but you have to create it in your project).

Ah glad I found this issue here; was very confused dropping this into a project new (as opposed to migrating an existing project) and it complaining about the template not existing 😆 came into the repo to see what was going on. I'll pull the widget from an older project and migrate across 👍

@ash-plunkett-alliance If it's a new project using @alliancesoftware/ui I can give you a minimal working version, it's just not a published version yet. If it's an older project using antd the previous widget should work

@davecoates It's a fresh clone of the template but it's not a real project, I was just toying around with some things.

Happy to test out a widget if you've got one though 👍

Started looking at some other projects that I'd previously migrated from common_storage -> AP storage and forgot they're also antd projects 😆

Consideration for the finalised widget: returning a more descriptive error from the API if file upload is rejected for not being a valid file type so that the frontend can display a nicer error. Currently it just returns a message-less 400.

(I've done some other tweaks to the widget as well; once I've played around some more I'll clean it up and post it here for consideration as well for the finalised widget in the future)
