Functions
int	modem_attest_token_get (struct nrf_attestation_token *const token)
	Gets the device attestation token from the modem. If successful, the base64url attestation string and base64url COSE string will be stored in the supplied struct. This function will allocate memory for the strings if buffers are not provided by the user. In that case, the user is responsible for freeing the memory by calling modem_attest_token_free.

void	modem_attest_token_free (struct nrf_attestation_token *const token)
	Frees the memory allocated by modem_attest_token_get.

int	modem_attest_token_parse (struct nrf_attestation_token const const token_in, struct nrf_attestation_data const data_out)
	Parses attestation token.

int	modem_attest_token_get_uuids (struct nrf_device_uuid dev, struct nrf_modem_fw_uuid mfw)
	Gets the device and/or modem firmware UUID from the modem and returns it as a NULL terminated string in the supplied struct(s).
