Arguments:
database -- A path to a valid MaxMind DB file such as a GeoIP2 database
file, or a file descriptor in the case of MODE_FD.
mode -- mode to open the database with. Valid mode are:
* MODE_MMAP_EXT - use the C extension with memory map.
* MODE_MMAP - read from memory map. Pure Python.
* MODE_FILE - read database as standard file. Pure Python.
* MODE_MEMORY - load database into memory. Pure Python.
* MODE_FD - the param passed via database is a file descriptor, not
a path. This mode implies MODE_MEMORY.
* MODE_AUTO - tries MODE_MMAP_EXT, MODE_MMAP, MODE_FILE in that
order. Default mode.
