v0.15.0

What's Changed

Deprecates @dfinity/authentication, moving the isDelegationValid check into `@dfinity/identity.

Also moves Secp256k1KeyIdentity out of @dfinity/identity to its own package, @dfinity/identity-secp256k1 in order to keep package sizes down for other packages.

@dfinity/identity-ledgerhq is deprecated, and had already been out of use for some time. @zondax/ledger-icp is the maintained tool for integrating with the Ledger hardware wallet.
