Need File.from_uri() method

[volkfox]

Description

There are multiple situations in datasets calling for introducing a new file object.

For one example, reading a dataset like Google OpenImage produces a URI column which needs conversion to File. For another example, extracting a bounding box from an image can be saved locally and added to dataset.

In all these cases, a dataset needs a new File/ImageFile/TextFile object created from URI, and a method to automate it, similar to:

TextFile.from_uri(uri, resolve=True)

where URI can be any supported locator (local, cloud, https), and resolve argument determines whether the URI is tested and more information gathered (e.g. filesize).
