Thomas Guillemard eeb626947e Implement Shared Fonts (#215)
* Implement Shared Fonts

This fully implements shared fonts.
This commit is provided without fonts.
This commit also add Size to HSharedMem.Positions to be able to add fonts to shared zones when RequestLoad is called.

* Require the user to provide fonts in RyuFS/system

* Use File.Exits instead of relying ona try/catch and change system resource exception format a bit

* Make sure that font sum doesn't exceed 17MB

Also rename font data dictionary for coherence.
