added modern static fixed frame buffer which actually allocates the memory intended and is readable. i doubt that this is mergable for erpc. I just created this PR because i was asked too :)

Thanks for the read though, it's sadly nothing special :/

how to build

• cd erpc && make CXXFLAGS='-std=c++17'
