this is the first step to replace this algo with v2. this algo is affected by a vulnerability that was addressed in v2.

This is as of commit bd64681958fae8b35b47f1c799bd2c2d3fc532c9 from https://github.com/bschn2/rainforest.git

Focus is on maximizing performance for low-power devices like RaspberryPi. Some performance reports available here for more context bschn2/rainforest#15 (comment) and indicate RPi being only half the performance of skylake 4 GHz, and 1080Ti being only 9 times faster than RPi.

this is based on latest updates which reduce the number of rounds and allocates only one rambox for all threads.
it roughly 50 times faster.
this new version includes the correct hash rate.
