Arcanist (Eldrich Font) - Arcane Reservoir

Arcane Reservoir points desappearing after rest. Please fix this (like magus reservoir), because in this state this class become absolutely useless in front of basic mage-tipe classes (because 3_main_stat_class must have something interesting to not prefer sorcerer/mage-trickster path)
(Maybe it work on other Arcanist specs)
