Add write functionality for authenticatorLargeBlob

[sirkrypt0]

It may be desirable to write data, such as un-/locking events, back to the large blob. That way, the data can be transported over the virtual network to some central system.

Implementation Notes

You'll likely want a structure similar to the already existing fido_dev_largeblob_get.

You might want to take a look at the implementation of the libfido2 in fido_dev_largeblob_set.
