Update dependency versions (#1265)

* Update versions of many dependencies

* Bump version of rand

* Updates for changed APIs in rand, ring, and webpki

* Replace references to `snow::Session`

`Session` no longer exists in `snow` but the replacement is two structs `HandshakeState` and `TransportState`
Something will have to be done to harmonize `NoiseOutput.session`

* Add precise type for UnparsedPublicKey

* Update data structures/functions to match new snow's API

* Delete diff.diff

Remove accidentally committed diff file

* Remove commented lines in identity/rsa.rs

* Bump libsecp256k1 to 0.3.1
