Currently we generate a disk image that we work on.
For reading we can use commit a92ab3c71e, however for writing things are a little more complicated.

We can improve the current implementation, by reusing some parts for the previous commit.

Idea:
Filesystem index will be an in memory array.
When reading/writing from/to a block use this array to lookup the associated file.
When writing, if the block is not associated with a file yet, store it in memory.
When the filesystem index is updated, check if the unassociated block is now associated with a file.
If it is now associated write it to the file and free the memory, if not keep it in memory.
