Skeleton calcPoW function that prepares payload for hashingFunction to increment Uint8Array nonce
Util function for converting a number to its Uint8Array representation
Actually perform calculate PoW nonce for every message
Adding bytebuffer as dependency and updated package-lock
Move PoW to new file and execute it in child process
TODO: Move send message logic to callback after child process has finished calculating the PoW
Refactored nonce calculation to function to be awaited
More readable timestamp grab plus converted to seconds
Nonce is now returned as a base64 string and included in request header
Also converted timestamp and ttl to string when including them in the header
Added a couple comments and tidied up some nonce logic
