T-Rex 0.19.7

* ("ethash", "octopus", "kawpow") Improve stability for 30xx series GPUs
* ("ethash") Verify overclock stability after DAG rebuild ("Instability detected" message is printed in case there are issues)
* Add "--gpu-report-interval-s" parameter to control hashrate summary report frequency based on the number of share submissions
* (API) Add new "pause" command for "control" handler to pause and resume mining
* (Watchdog) Display a list of GPUs caused miner restart with "GPU is idle" error

Bug fixes:
* ("x21s") "incorrect size of extranonce2" error
* (UI) Incorrect GPU index in share submission report when "--pci-indexing" mode is enabled
* (API) Miner fails to switch algorithms on the fly for some ""<algo_from>" -> "<algo_to>"" combinations

Completely unreliable for a 7 card 30series rig with medium memory overclocks 3060Ti +800MHz, 3070 +700MHz and +800MHz, 3090 +350MHz... It cannot create the DAG reliably it will hang and crash miner. However if memory overclocks are reduced by 200MHz on each card it will create DAG why is this? It works perfectly with version 0.19.5 and 0.19.4 (these I have tested with these settings).

This is absolutely not a stable build for me... It just hangs unless used with an extremely low memory overclock.

I have the same issue oddly enough with a 9 GPU rig, my 8 and 7 GPU 3060ti rigs work with no issues.
I also freeze on DAG generation at the start of mining causing the rig to reboot.
