filesystem: add unit tests for encoder/decoder methods

Lets add test vectors for the per-record/per-file encode/decode of
our various classes for the Elementary Files.

We keep the test vectors as class variables of the respective EF-classes
to ensure implementation and test vectors are next to each other.

The test classes then iterate over all EF subclasses and execute the
decode/encode functions using the test vectors from the class variables.
