 The proof-of-work equation for Nano cryptocurrency is defined as `blake2b(nonce||blockhash)>=threshold` where blake2b is the hash function configured for an 8-byte output, nonce is a random 8-byte value, || is concatenation, blockhash is a 32-byte value, and threshold is 0xfffffff800000000.
 
 My code currently finds valid nonces on a gaming GPU without issue but only because the initial search space is so large due to using a workgroup size of 256 and a dispatch of (256, 256, 256), so the probability of finding a nonce in the first pass is extremely high. However, this does not perform well on less powerful hardware like smartphones. Please alter my code to perform the nonce search in `main()` in a loop until a valid nonce is found with the idea that a smaller workgroup size and/or smaller dispatch dimensions can allow weak hardware to nonetheless iterate through nonces to search for a valid one and return it.
