Include Filesystems Visualizations

[bhuvy2]

Is your feature request related to a problem? Please describe. Almost all of the images in the filesystems chapter were off by a bit because they were taken from other textbooks. Ideally, we should draw our own versions of the images for the ext2 file system.

Describe the solution you'd like

• Picture of an inode
• Inode pointing to direct and indirect blocks
• How a file would fill up an inode with direct and indirect blocks.
• How inodes and blocks are laid out on disk.
• Maybe a picture of raid?

Describe alternatives you've considered N/A

http://aneeshdurg.me/what_is_a_filesystem/ is now live and does some of these things!

The content there assumes that the reader is on a supported browser and is kind of an interactive experience, so I don't think it can really made into a part of this book, but maybe some of it can be integrated here?
