Extra methods

[christianbundy]

It looks like Sodium-Native API is a subset of the libsodium API, but the Sodium-Javascript has some extra methods not found in either:

• crypto_verify_16
• crypto_verify_32
• crypto_box_ZEROBYTES
• crypto_box_BOXZEROBYTES
• crypto_box_BEFORENMBYTES
• crypto_generichash_WASM_SUPPORTED
• crypto_generichash_WASM_LOADED
• crypto_generichash_ready
• crypto_generichash_instance
• crypto_secretbox
• crypto_secretbox_open
• crypto_secretbox_ZEROBYTES
• crypto_secretbox_BOXZEROBYTES
• crypto_shorthash_WASM_SUPPORTED
• crypto_shorthash_WASM_LOADED
• crypto_stream_xor_instance
• crypto_stream_chacha20_xor_instance
• crypto_stream_chacha20_ietf_xor_instance

There are three types of extra methods:

• Methods found in libsodium but not Sodium-Native.
• Methods specific to WASM (maybe generichash_ready should be generichash_wasm_ready?)
• Methods suffixed with _instance, which were previously in Sodium-Native but have been removed (replaced by _init, _update, and _final?).

Should any/all of these be removed or replaced?

After talking about this a bit in IRC, it sounds like methods can be removed if:

• They're not in sodium-native.
• They're don't mention wasm.
• They aren't _instance legacy methods.
