Update: FSS Embedded Read memory allocation logic.

Update: FSS Embedded Read memory allocation logic.

Move the internally managed allocation into externally managed allocation.
This allows for better memory control and optimization by the caller.

The use of `f_memory_array_increase()` is incorrect in several cases.
Switch to `f_memory_array_resize()`.
Add 2 when resizing to account for the depth position but also an additional element as a minor memory allocation optimization.

Get rid of headers that should not be included.

This does not address any of the other problems with the FSS Embedded Read functions.
