Nested entries

[TheCymaera]

It is common for IDEs and game-engine editors to specify resources using URIs or file paths.

To access a deeply nested file, we need to call getFileHandle and getDirectoryHandle recursively. Each level is an asynchronous operation that needs to be run sequentially.

I propose that the getFileHandle, getDirectoryHandle, and removeEntry methods be overloaded to accept an array/iterable argument.

directory.getFileHandle(["path", "to", "file.txt"]);

Alternatively, file names should accept slashes as delimiters.

directory.getFileHandle("path/to/file.txt");

The options parameter should include a createRecursive flag to complement the create flag.

directory.getFileHandle(["path", "to", "file.txt"], { createRecursive: true });
// Creates:
// path/
// path/to/
// path/to/file.txt

You can easily implement it yourself, not sure if there would be an advantage in making the spec more complicated for that?

Each level makes at least one file system call to check if the file exists. This takes anywhere between .2 to 1 milliseconds on the devices I've tried. The difference adds up quickly when processing multiple files.
