`config` was being consumed much too early before it has a chance to
call `load`. This caused GPU to read weird uninitialized data, and then
`load` called, and then further initialization to occur based on default
data and the data inside of `config.toml`. `EmulatorConfig` needs to be
loaded in first before any sort of initialization happens, by adding a
new constructor so that it can be initialized sooner.
There are still some initialization errors to work through, such as
config not being initialized properly by the time GPU tries to utilize
it too. Also some life-time issues. But manually forcing it to use the
Null backnd successfully works and allows games to be "played"
headlessly.
