Add slash for dir in ipfs files ls

[overbool]

We can get the follow result using ipfs files ls:

dir-a
dir-b
a
b
c

Is this a good advice that add the slash for directory to distinguish directory from file?

just like the follow:

dir-a/
dir-b/
a
b
c

We can but, unfortunately, this will force us to fetch the first block of every file to resolve the type. However, I don't think this'll be that much of an issue in practice, especially for MFS. This is also what ipfs ls does so we should probably just mirror that.

Thoughts @schomatis?

We could add the slash when using the -l flag which already fetches that information,
