The functionality of stat is split into smaller sub-functions, which allows
to reuse them more flexible, as the code flow is similar but not always the same.
By this, the ugly and incorrect re-setting of the i-node in the lookup callback
function is avoided.
The correct i-node is now calculated beforehand and stat simply creates a
`libc::stat` struct from the provided parameters.
Also, this fixes incorrect i-node assignments in the readdir callback function.

The lookup call checks if the given filename is found in the directory referenced
by the i-node by calclulating the filenames hash and looking it up in the
directories goodbye table.
If found, the entries parameters are returned.
In order to be able to lookup the parent offset by a given file offset in the
readdir callback, this also stores the corresponding values in a HashMap.

Also, removes an unused println statement in the decoder callback function and
fixes a typo.
Further, use ABI compatible Option<&T> for FFI to avoid use of raw pointers.

This adds the basic code in order to create a fuse session and mount an archive.
It adds libfuse3-3 as runtime dependency and libfuse3-dev as build dependency.
