Track all dynamically allocated memory within the work struct by copying work structs in a common place, creating freshly allocated heap ram for all arrays within the copied struct.
...
Clear all work structs from the same place to ensure memory does not leak from arrays within the struct.
Convert the gbt coinbase and stratum strings within the work struct to heap ram.
This will allow arbitrary lengths without an upper limit for the strings, preventing the overflows that happen with GBT.

Windows' timer resolution is limited to 15ms accuracy. This was breaking dynamic intensity since it tries to measure below this.

Since we are repeatedly sampling similar timeframes, we can average the gpu_us result over 5 different values to get very fine precision.
