fix(picrypt): use crypto_box_* constants for public-key decrypt

Browse Source 
The decrypt() function for crypto_box (public-key) used
crypto_secretbox_NONCEBYTES and crypto_secretbox_MACBYTES
(secret-key constants) instead of crypto_box_* constants.
These happen to be equal in libsodium but are semantically
different APIs. Fix ensures consistency with the encrypt()
counterpart.
