Function init_dora_context_from_env 

#[unsafe(no_mangle)]
pub extern "C" fn init_dora_context_from_env() -> *mut c_void

Initializes a dora context from the environment variables that were set by the dora-coordinator.

Returns a pointer to the dora context on success. This pointer can be used to call dora API functions that expect a context argument. Any other use is prohibited. To free the dora context when it is no longer needed, use the free_dora_context function.

On error, a null pointer is returned.
