This will allow later more gpu candidates.
Note: This is an unfinished work, we keep the previous behavior for now
To finish this, all algos solutions should be migrated and submitted nonces attributes stored.
Its required to handle the different share diff per nonce and fix the possible solved count error (if 1/2 nonces is solved).
which display submitted block and net difficulty and is able
to detect shares above net diff (solved blocs)
Note: only made on lyra2v2 and zr5 algos
TODO: compute the found diff on all algos...
require changes in all scan hash "kernel" function parameters
to be continued...
