fetchURL() should be named differently

[LeaVerou]

It's confusing that there is a $gf.media.fetch() and a $gf.media.fetchURL(), since the former also returns a (blob) URL.

Brainstorming:

• toURL()
• getURL()
• getBlobURL()
• toObjectURL()
• getObjectURL()
• createObjectURL() (to parallel the native method, since this seems to be a thin abstraction over it)

The first just returns a Blob, not a URL.

$gf.media.fetchURL() is essentially:

URL.createObjectURL(await $gf.media.fetch(...))

plus some caching to prevent generating multiple URLs that point to the same Blob.

Maybe $gf.media.fetchObjectURL()?
