Observed behavior:

• User sets LIBMONGOCRYPT_PATH variable incorrectly
• User attempts to use FLE
• An error is raised telling them that the LIBMONGOCRYPT_PATH is invalid
• User fixes LIBMONGOCRYPT_PATH
• User attempts to use FLE
• The libmongocrypt binding says that it has no method "mongocrypt_init"

Even though the user fixes the LIBMONGOCRYPT_PATH env variable, the Ruby Binding class is not reloading, which means that the binding does not know the location of the C library and FLE will not work unless the driver is restarted.

Expected behavior:

• User sets LIBMONGOCRYPT_PATH variable incorrectly
• User attempts to use FLE
• An error is raised telling them that the LIBMONGOCRYPT_PATH is invalid
• User fixes LIBMONGOCRYPT_PATH
• User can use all features in FLE
