### Contribution description
This PR adds a temporary RAM file system. It uses dynamic memory allocation (malloc/free, but this can be overwritten with defines and could be improved later on) to allocate RAM files.
The file system is based on a chained list of files, each file containing a chained list of buffers.
There is no support for directories.
