        /*
         How to fix TrialPassStates offsets. Detailed example.

        Update. New way: Uncomment argument (StaticOffsetFieldDebugAttribute) from:
        public static int DebugPlayerTrialStates
        Use "Qvin Debug Tree" plugin. Change slider DebugPlayerTrialStates to pick the right offset. Convert slider number to hex

        Old way:
         Better to use ReClass.Net for that (or program that can show bits of byte on some offset)
         Go to some uncompleted trial but do not activate it!
         Open ReClass on Player component address (get it from "Qvin Debug Tree" (QDT) plugin)
         Scroll to offset near (0x180) (Use "Add bytes->2048" command to increase view range).
         Switch all next data to display as bits (better to switch them to Hex8 first, then to bits, to see bits of each byte on a new line)
         Detect which bit is changed after activating trial (make 2 screenshots then compare)
         In my case I got this:
            0x180:  11000000
            0x181:  01111111
            after activating "The Bath House" trial:
            0x180:  11000000
            0x181:  11111111   <<here
        so after activating trial the last (8) bit of 0x181 byte was changed (count bits from right to left).
        Open in QDT GameController->Files->LabyrinthTrials->EntriesList. Here we can see that area Id of "The Bath House" trial is 272
        So the 8th bit of 0x181 byte is "The Bath House" trial
        The first trial (Lower Prison) id is 263 (at this moment), so Bath House is 272-263= 9th bit from our data bits,

        Byte have 8 bits (yes, obviously), so we going to start read bytes array data from 0x180 (ignoring first 7 bits)
        And to simplify it we will read whole array (286 bits (as 286 is the last trial area id) = 35,75(36) bytes).
        So 263 - 7(skipped) = 256.  256/8bits = 0x20 back from 0x180. So 0x180 - 0x20 = 0x160. Read offset is 0x160
