FR add obsidian uri for local files

[Jopp-gh]

Since Obsidian 1.2.8 we're unable to load local urls, so the only way to load files, like images requires online access by now.

An ideal substitute to local url would be obsidians uri, see https://help.obsidian.md/Concepts/Obsidian+URI

Now, for the implementation I'd imagine a file picker, then a string parsing to add %2Ffor path slashes and %20 for name spaces.

Why this feature request?

• I want to load local files
• the file picker would be user friendly, otherwise other apps are needed to copy file paths and to add file path additions - a cumbersome process
• Style Settings is a super useful plugin for themes and because of its popularity, should provide support to load local files as well.
