Split library into modules (#20)
* crypto_stream: signature change needed to modularise

* move ed25519 arithmetic to separate module

* module: poly1305

* module: crypto_scalarmult

* module: crypto_hash

* module: crypto_sign

* module: crypto_secretbox

* move verify functions to crypto_verify module

* leftover crypto_stream functions

* module: crypto_onetimeauth

* module: crypto_box

* tidy up

* require ed25519.js

* update: crypto_hash

* add chacha20; align API with PR#21

* update sha512 to wasm module

* fix bugs in crypto_sign

* be standard

* add: crypto_box_seed_keypair; alias crypto_kx methods to crypto_box

* scalarmult: import curve methods; be standard

* correction: crypto_kx is not actually an alias of crypto_box

* export _9 constant field element

* add: crypto_box_seed_keypair

* removed duplicate module.exports declaraion

* declare constants about exports

* rename memzero -> sodium-memzero

* update sodium_memzero function to arr.fill(0)

* tidy: remove legacy functions

* added: crypto_aead_chacha20poly1305_ietf methods

* listen to linter

* add assertions

* chacha: readUint32Le generalised for uint8array; aead: standard fix

* add null check on ad param

* added: sodium_memcmp

* export sodium_memcmp

* export crypto_verify module

* sodium_memcmp returns boolean

* added: sodium_is_zero

* catch syntax error

* throw if crypto_aead cannot validate, fix typo in crypto_verify

* move chacha20 alg to external module

* use Uint8Arrays instead of buffers

* change checks to assertions

* bump to chacha 1.0.3 - remove Buffer dependency

* reduce code branching, align return values with sodium-native

* add sha-wasm deps to package.json

* standard fixes

* bump chacha20 to 1.0.4: remove Buffer dep

* move crypto_hash_sha256 to module to uncouple wasm dependencies

* add endian check: all other modules require members of this set

* correct filename: crypto_hash_sha256

* export constant: crypto_hash_sha512_BYTES
